PHP and it’s Career Prospects .
PHP Programming at present day:
PHP is a scripting language used predominantly for web programming. It is very popular mainly because it is open-source and you don’t have to buy a license or copy to install it on your computer, and the websites created using it are very dynamic and attractive.
PHP community is very active and solutions for any technical problem can be found online, either on websites, blogs or forums. According to a Netcraft survey, more than 100,000,000 hostnames have PHP coding and it is installed on more than 20 million websites and one million web servers. Popular websites such as WordPress use PHP as their publishing tools.
How long will it take for me to learn PHP? Do I have to take a course? To learn PHP, it is very important to learn C and C++ since most of its run time code is made of C libraries and it is also scripted in C.
PHP is very easy to learn – it is a straight-forward language and does not have many complexities. When I was doing my under graduation in Computer Applications, a basic PHP course was offered to us as part of extra credits. We all could write a simple, functional script in a matter of minutes. There are dozens of websites that provide free step-by-step guides to learn PHP so much so that you can become a master of the language just by self-study.
A living example is my dad who, at age 70, is trying to learn PHP to improve the functionality of his website on temples which is his retirement hobby. He was able to succeed just by reading online tutorials. If a 70-year-old can do it, I am sure you can too!! What do recruiters look for in PHP programmers? PHP programmers who are skilled in languages like C, C++ and Java, and also keep abreast of the latest developments in mobile and wireless technologies, are in great demand.
A Bachelor’s degree in Computer Science or Computer Applications is a necessary criterion to join most companies as a PHP programmer. But, a Bachelor’s degree in any stream along with a certification in PHP can also work. What can I do as a PHP programmer? With knowledge of PHP, you can become a Smartphone application developer and make a lot of money, while having fun at work! Various web development companies require PHP programmers to develop websites for their clients. You can also freelance and work independently for clients. If you know other related web programming languages, you can sit at home and build a prosperous career.
What is the remuneration like? According to PayScale, web developers earn an average salary of Rs. 3-6 lakhs per annum. As a fresher, you will start at about Rs. 10,000-20,000 per month, but with experience your salary can go up to Rs 12 lakhs per annum. Where can I find jobs with my PHP skills?

Is coding a programming language?
Coding is a computer programming language that helps to communicate with a computer. Computers do not understand human languages. Coding allows humans to communicate with the compute.
Why is coding important?
Dennis Mac Alistair Ritchie ,an American computer scientist invented “CODING”.
It is using a language that a computer understands to give a computer instructions in order to perform specific functions. Coding allows us to create things such as computer software, websites, apps and video games. There are various types of different code, depending on what you want to develop.
Coding is a computer programming language that helps to communicate with a computer. Computers do not understand human languages. Coding allows humans to communicate with the computer. Coding is a process of establishing a successful communication between a software program and the computer hardware. The compilers translate the program into assembly language. The coding process converts the assembly language to Binary Coded Signals, whereas Programming is passing the instructions and information to the computer that describes how a program should be carried out. Programming helps computers to perform certain actions. Various types of programming languages available in the market, like C, C++, Java, Python etc., help develop new and creative technology.
Definition of Coding:
Coding is an act of translation. It writes the user’s instructions in the form of a computer program. It converts the computer program into low-level language codes and feeds it to the computer for execution.
Definition of Programming:
Programming is an act of designing and developing a logical software solution to the problem statement. It involves designing and developing the algorithms, flowcharts, and implementing the solution using a programming language.
Which programming language is best for applications?
Python and C++ are two of the best programming languages for software development, though each language has its ideal uses. Python is versatile in its practical applications; developers often use it to power artificial intelligence, machine learning, web, and development.
Some common object-oriented programming (OOP) languages include:
- Java. ,Python., PHP, C++ , Ruby.
Which coding is better for future?
JavaScript is considered to be an ideal programming language if the objective is to create dynamic web elements such as animated graphics, interactive maps, etc. As this language is extensively used in web development, building web servers, game development, etc., you know how much of scope it beholds.
Why is programming now called coding?
What’s The Difference Between Coding and Programming? While coding and programming have a lot of overlap, there’s one main difference. Coding describes one particular skill: the act of writing computer code. Programming involves coding, as well as a range of other, related web development skills.
Which is most powerful programming language?
There are many powerful programming languages in existence, but the most powerful one is undoubtedly C++. C++ has the ability to scale up or down depending on the needs of the user, making it an incredibly versatile tool.
What is the fastest programming language?
“C” is called as Mother of Programming Languages. One of the most important factors to consider when ranking programming languages is speed. C++ is the fastest language according to a number of measures, including compilation time and execution speed. In this section, we will look at some ways in which C++ beats out other programming languages in terms of performance.
What are the 4 types of programming?
Functional Programming Language. Scripting Programming Language. Logic Programming Language. Object-Oriented Programming Language.
What is coding known as?
What is coding? Coding, sometimes called computer programming, is how we communicate with computers. Code tells a computer what actions to take, and writing code is like creating a set of instructions.
Python, as known to many, is a server-side language that is not just easy but also widely used. Python is a computer programming language often used to build websites and software, automate tasks, and conduct data analysis. Python is a general-purpose language, meaning it can be used to create a variety of different programs and isn’t specialized for any specific problems.
As good as artificial intelligence (AI) has become in answering queries and writing code, there will still be a need for developers

Angular and it’s vision for the future
Angular and it’s vision for the future.
Angular is an open-source front-end JavaScript framework used primarily for developing single-page web applications (SPAs) and dynamic web applications.
In addition to components and modules, Angular also relies heavily on dependency injection, which allows components and services to be easily injected with the dependencies they require. This promotes modularity and reusability by separating concerns and allowing components and services to be easily tested in isolation.
Another key concept in Angular is data binding, which enables synchronization between the model and view. There are several types of data binding in Angular, including interpolation, property binding, event binding, and two-way binding.
Angular also provides a robust set of directives, which are used to manipulate the DOM, apply styling, and add dynamic behavior to components. Directives can be either built-in or custom, and they are a powerful tool for creating reusable, declarative code.
Finally, Angular provides a comprehensive set of tools for managing application state, including observables, pipes, and the RxJS library. Observables enable asynchronous programming, while pipes provide a convenient way to transform data in templates.
Overall, Angular’s architecture is designed to promote modularity, reusability, and efficiency, while providing a rich set of tools for creating complex and dynamic web applications.
Angular is a popular JavaScript framework used for developing single-page applications (SPAs) and web applications. The framework is based on a set of fundamental concepts that form the architecture of Angular applications. These concepts include:
- Components: Components are the basic building blocks of an Angular application. They define the views of the application and are responsible for rendering the user interface (UI). A component encapsulates the HTML template, the logic that controls the view, and any associated styles.
- Modules: Modules are collections of related components, services, and directives that form a functional unit of the application. A module can be used to organize the application into logical blocks and to provide lazy loading of code.
- Services: Services are used to provide functionality that is not directly related to the UI. Services can be used for data access, validation, logging, and other tasks. They are typically singleton objects that can be injected into components as dependencies.
- Directives: Directives are used to add behavior to the HTML elements in the application. They can be used to create custom HTML tags, modify the behavior of existing tags, or provide reusable UI components.
- Templates: Templates define the structure of the views in an Angular application. They are used to bind data to the UI and to define the behavior of the components.
- Dependency Injection: Dependency Injection (DI) is a design pattern used in Angular to manage dependencies between objects. It allows for the creation of loosely coupled components, making the code more modular, reusable, and efficient.
- Angular application is defined by a set of Ng Modules. These modules are used to organize the code into logical units and to provide lazy loading of code. The modules can be used to manage dependencies between the components and services in the application. Overall, these fundamental concepts form the basis of the architecture of Angular applications, making it a powerful and flexible framework for building modern web applications.
There are certain fundamental concepts on which the architecture of Angular applications depends. The basic building blocks of the Angular framework are Angular components that are organized into Ng Modules which collects related code into functional Angular can choose among and modify according to your program logic and data. Components define views , which are sets of screen elements use services, which provide specific functionality not directly related to views. Service providers can be injected into components as dependencies, to make code modular, reusable, and efficient. An Angular application is defined by a set of Ng Modules .
What are the types of Angular?
Angular has all the versions which came after Angular JS (Angular 1), Angular 2, Angular 4, Angular 5 and now Angular 6. It has the latest and most refined framework till date to design a web application that is dynamic and responsive.
What is good about Angular?
Angular offers powerful DI instrument and services to resolve various productivity issues and speed up the development process as efficient problem solving patterns: Dependency Injection (DI) is a design pattern that makes it possible to improve the efficiency and modularity of an application. Classes, Modules, components and services are that use decorators
Decorators are used by modules, components and services
These decorators mark their type and provide metadata that tells Angular how to use them. View is defined as the metadata for a component class associates it with a template. A template combines ordinary HTML with Angular directives and binding markup that allow Angular to modify HTML before rendering it for display.
The metadata for a service class provides the information Angular need to make it available to components through dependency injection ( DI).
Each of these subjects is introduced in more detail in the following pages.
Introduction to Modules.
Introduction to Components. Templates and views. Component metadata. Data binding. Directives. Pipes.
Introduction to services and dependency injection.
Features of Angular:
Any app size. Start quickly. You can start small knowing that Angular’s tools support your apps as they grow. …
A great community. Community resources. …
Build productively. Powerful command-line interface. …
For everyone, everywhere. Internationalization tools.
Scope of Angular:
The scope is the binding part between the HTML (view) and the JavaScript (controller). The scope is an object with the available properties and methods. The scope is available for both the view and the controller.
Why use Angular instead of JavaScript?
Angular empowers developers to build rich internet applications (RIAs) more easily. Where many JavaScript frameworks focus on expanding the capabilities of JavaScript itself, Angular instead provides methods for enhancing HTML. Angular expands the capabilities of HTML beyond being a simple markup language
Why Angular is called framework?
Angular is considered a framework which offers strong opinions how application to be structured and moreover much more functionality out of the box, don’t need to decide routing libraries to use, just start coding.
What is difference between React and Angular?
Angular is a full-fledged framework, while React is a JavaScript library.
Why Angular is a platform?
Angular is a development platform, built on Type Script. As a platform, Angular includes: A component-based framework for building scalable web applications. A collection of well-integrated libraries that cover a wide variety of features, including routing, forms management, client-server communication, and more.
Businesses are striving for an ultra-effective online presence these days. Hence, the need for a robust web development framework with cutting-edge features is at an all-time high.
Angular is a highly popular web development framework that offers rich user experiences, fast responsiveness, and code maintainability. It is one of the most sought-after JavaScript frameworks and is aimed to make front-end development much simpler and accessible.

Front-end development and its reality
Front-end development isn’t real development?
There is some sentiment out there that front-end development isn’t real development. It’s a swaggering, trollish sentiment. Still, it’s fun to puff our chests back sometimes. Let’s try to put a point on why front-end development is every bit as difficult and worthy of the title as any other subset.
The practice of front end development is similar to playing the bass: it’s easy to learn but difficult to master. There is a lot more to it than HTML and CSS
We have to deal with cross browser compatibility.
This was far and away the most cited gripe in the group. While Internet Explorer continues to be the brunt of most jokes, every browser has its own quirks that often require special development techniques to overcome.
It’s rather expected of us that we know how to build websites that can work cross-browser. We should know what browsers support what and how to debug and overcome browser-specific issues. We should know how to do emulate or otherwise test on a variety of browsers.
We should know tools that help us with cross-browser problems either automatically or enable us to write code to handle situations of support and nonsupport of features. We should know how to do fallbacks. We should know about progressive enhancement and graceful degradation.
Cross-browser compatibility is a hugely complex development task.
In addition to dealing with browser inconsistencies, front-end developers are also charged with developing for as many screen sizes, screen orientations, pixel densities, and input types as possible.
The burden of the massive landscape of different screens, browsers, and capabilities lies most heavily on front-end developers.
Frameworks, libraries, preprocessing, dependencies, plugins…
It used to be that linking up a stylesheet and maybe a JavaScript file in the HTML was all that was needed to start designing and building a site. In fact, that’s still the baseline.
Today’s development feels a lot different. The toolchain is a lot thicker. We’re making choices about build processes, which libraries to use, what languages to write in, how invested in future syntaxes we want to be, how much we want to depend on frameworks, which third-party tools make sense and feel safe to use.
Not only is it fatiguing to think about the choices, it’s increasingly difficult to know what the best choices are and if these choices are smart in the long term.
There are just as many choices, or more, at the front end level of development than there are anywhere else. Not to mention the landscape moves extremely quickly.
Many of today’s frameworks and CMS’s, straddle the line between lots of different disciplines. Front-end developers are right in the middle of it all. We’re ultimately responsible for design—how the site looks. We’re helping content people ensure they have what they need and they give us what we need. We’re working in templates prying out the data we need in the formats we need. We’re handling user input and ensuring it funneling where it goes for more back-end concerns.
The barrier to entry for front-end development is fairly low. Everyone has heard of HTML. They “know enough to be dangerous” as it were. Because that barrier is low and because it’ so easy to dabble, it makes sense people assume there isn’t that much to know and that front-end development isn’t particularly difficult.
the maxim about naming things being one of the hardest problems in computer science. Us front-enders are naming things all the time. Class names and IDs, data attributes, file names, communicating patterns with your team. It’s endless. It feels like there are dozens of name choices on an average day.
Not to mention the task of copywriting often falls to us, which isn’t quite naming but is in a similar vein of difficulty.
“The right way” and “the wrong way” aren’t as cut and dry as with back-end development.
In back-end development, if what you are expecting to happen happens, you’ve succeeded. Surely they are different ways to get there, some better than others. But in front-end development, the paths to completing a task seem endless. Even if you’ve seemingly succeeded, it can feel like just a matter of time until a bug is found in how you’ve done it.
CSS is very hard to test.
Back-end languages (and even JavaScript) can use unit testing and integration testing to help make sure the code works as expected. CSS has no such luxury. There are certainly people trying and there is some information and tools out there. But none of it is all that great and there are very few success stories.
Bugs can be subtle, confusing, and unexpected. Worse, a seemingly little change may have an adverse effect in an unexpected place where you don’t notice until it’s too late.
There are linting tools, which help a little. There are some style guide enforcement tools, but they don’t really help enforce more important things like adherence to naming standards.
Front end developers need to hold a very strong understanding of the entire website in their head in order to be most effective and efficient.
JavaScript is just as complex as any other programming language. It’s weird and hard.
JavaScript is front-end development. JavaScript is programming. Programming is part of software development. Software development is hard.
The rule of thumb is that 20% of the waiting for a website to load is from back-end concerns. Once HTML document has arrived, the rest of loading time is the concern of front-end developers. What resources are loaded, how many resources are loaded, how optimized they are, in what fashion they load in and how that feels, etc.
It’s where accessibility happens.
Building sites that are visually stunning is one thing and the accessibility of them is another. Designers care very much how users interact with a site and that might not always be a visual interaction. Designing and developing for disabilities is a discipline unto itself, but is most tightly tied to front-end development. Accessibility has its own set of specifications that sadly aren’t typically taught along with traditional front-end development training.
It’s hard to hire for.
Front-end developers are typically the hardest seats to fill. So front-end development is“real” development.

PYTHON AND AND ITS FRAMEWORK
PYTHON AND AND ITS FRAMEWORK
Django is a free and open source web application framework written in Python. A framework is nothing more than a collection of modules that make development easier. They are grouped together, and allow you to create applications or websites from an existing source, instead of from scratch.
This is how websites – even simple ones designed by a single person – can still include advanced functionality like authentication support, management and admin panels, contact forms, comment boxes, file upload support, and more. In other words, if you were creating a website from scratch you would need to develop these components yourself. By using a framework instead, these components are already built, you just need to configure them properly to match your site.
The Official Project Site describes Django as “a high-level Python Web framework that encourages rapid development and clean, pragmatic design. Built by experienced developers, it takes care of much of the hassle of Web development, so you can focus on writing your app without needing to reinvent the wheel. It’s free and open source.”
Django offers a big collection of modules which you can use in your own projects. Primarily, frameworks exist to save developers a lot of wasted time and headaches and Django is no different.
Django was created with front-end developers in mind. “Django’s template language is designed to feel comfortable and easy-to-learn to those used to working with HTML, like designers and front-end developers. But it is also flexible and highly extensible, allowing developers to augment the template language as needed.”
If you’re going to be working with Python, especially for web applications or web design, you’ll want to remember the Django framework. It will certainly come in handy.
CherryPy is another Python-based framework that is great to work with, although it is designed with the absolute minimalist in mind. It’s a framework you’ll want to explore after you already have some experience working with Python.

JavaScript frameworks for quick software development:
The popularity of Java script grows every day. It’s definitely the best scripting language which allows creating exciting interfaces and simplifies the development of web applications, being a perfect open source app development software and making the sites interactive and convenient to use.
The Javascript web development frameworks are issued and updated daily and that’s why it is difficult at times to go with the tides and understand which famework is most suitable and best matching for the project.
Before choosing a web app framework to apply the requirement and needs of the project to be taken into consideration.
The advantages of the frameworks
Javascript framework is a number of features and functions written in Javascript language and ready for the usage of the developers. These features simplify the interaction between the app and server and speed up the manipulating of the web page or app elements.
The main advantage of using a web application development frameworks is the fact that it provides immediate reaction to the user interacting with the site immediately.
The basic content of the traditional sites without frameworks is stored on the server and any new content , which is necessary to be upload requires reloading of pages. When frameworks are used , only the necessary blocks of a website are reloaded.
Some of the most advantageous benefits of the frameworks ‘usage:
- COST: The cost of the app development for websites decreases due to the JavaScript frameworks because they are free and open source code.
- Development speed: Java Script frameworks have good documentations. Some of the JavaScript frameworks are supported by such giant companies as Google etc. Due to such a lot of information, the speed of development increases.
- Efficiency: The usage of the pre-created functions and templates allows to carry out the projects more effectively. The developers have to write less code, which results in delivering projects meeting higher standards and more quickly.
Most used and popular frameworks—
JavaScript frameworks have now become one of the most preferred web app development platforms for modern single page apps, social networks, e-commerce products and other software solutions creation.
At present, without using frameworks, the development of modern web products has become almost impossible. There are Some companies are still using classical Java Script software incurring higher development costs. As a consequence of classical JS complexity, lot of frameworks have appeared in the market, but the solid leadership in the software development market belongs to these three: Angular, React and Vue.
Angular
Angular is a cross-platform framework which keeps to the MVC architectural pattern and supports a weak link between the display, data and logic of the components( integral parts of the app). Angular shifts a certain part of server services to the client side and consequently the server workload decreases and the web application becomes lighter.
Due to Typescript the project code becomes clear , convenient for developer’s understanding and contains fewer errors. Angular strong points are remarkable documentations and references.
One of the week points of Angular is the high learning curve for the projects because a JavaScript developer should know for instance , Type Script to start working with framework. It consequently makes the project fulfillment more difficult, especially the work is passed from one team to another. Another drawback of the Angular framework is the frequent release on the new versions. The 8th one already released in June, 2019.
React.js
React—is a java script library with open source code for user-interfaces development. For the first time React was used in 2011in the face book newsfeed, then in 2012 in Instagram.
React is still being developed and supported by Face book and Instagram. It can be used not only for browser-based web apps but also for mobile apps. The aim of the framework is to provide high speed , simplicity and operability of the apps on various platforms.
However, React is not a full-fledged Framework, but a function library. To use it as a Framework, other third party libraries should be attached. React strengths are speed, lightweightness, cross-platform format and big community.
The weakness is the necessity to use third party libraries for complete work which complicates the development process. Another drawback of the library is that it does not follow the standards in HTML or CSS CODE AS Angular and Vue.js do.;
Vue.js
Vue– is a progressive framework for user interfaces creation. Vue was made fit for gradual implementation unlike Angular or React. It means progressive framework gradually starting from certain pages, which makes the development much easier. The Vue.js creator is Even and You and the framework is widely used in Chinese companies. Not so long ago the repository management GitLab also switched to Veu.js.
Vue deals with presentations layer tasks in the first turn, it simplifies the integration with other libraries and existing projects. Vue coopted the best features of Angular and React- the speed and lightweightness and the possibility to support such technologies as Type Script and JSX. However along with this the Vue frame remained true to the principles of CSS and HTML code writing. It facilitates quick web application development and makes the processes of project development and support easier.
Thus , for any developer who knows the basics of the front-end technologies will not be a problem to develop or support the projects on Vue.
At present, a small community can be called a weak point of the Frame work as no big corporations support it. Nevertheless, popularity of the framework grows every year.
What to choose?
Every project is unique in its own way and before starting the project detailed analysis and evaluation is required.
However, there are certain key aspects, which help to choose a particular technology for development:
Speed and simplicity of project development and support.
The speed of the development depends on the technologies, already used in the projects. In case Type Script or JSC have already been applied then Angular or React correspondingly needed. But in case the project from scratch, it’s better to choose Vue .js due to its compliance with standards.
Trends:
All the frameworks are popular and will keep the leadership in the modern development marketin the coming years. It will not be a mistake to choose any of them . However Vue is vigoursly gaining popularity, followed by React.
Mobility and Stability:
Supposing one framework is chosen and then decided to switch to another one and Vue. js is the best choice in this case because re-writing the projects on Angular or React will mean that the developers will most likely need to switch Type Script or JSX code to classical Java Script and HTML correspondingly.
One more important aspect to consider is the frequency of Frameworks update. Angular has serious updates issued every 06 months, React approximately once in a year. Vue is more stable in this sese and has serious updates once in several years.
