PHP Full Form and Overview

Here in this article, we’re going to discuss what php is, php full form, different versions of php, and a short overview.

As you may know, PHP is one of the most widely used languages for web development; it is an open-source platform where every web developer can start coding. There are two types of programming languages:

  • Client-side programming language;
  • Server-side scripting language

PHP is a kind of server-side scripting language that came into existence in 1994, and the language embeds itself in HTML. The general purpose of this language is for web development.

Now, what is a server-side scripting language?

Server-side programming language works on a server, which means the program runs on the server-side and not on the client-side. In simple words, when the client request pages from the server and server perform the operation and give the output, then it is known as a server-side scripting language. The central role here depends upon the server.

PHP Full Form

Furthermore, websites like, Wikipedia, Yahoo, etc. are built on php as it is the most convenient and open-source platforms.

PHP Flow Chart Diagram

The diagram below showcases the architecture of PHP and how it works on the server and handles the request.


Step 1: The client requests a specific page from the server.

Step 2: The request is sent from the client-side to the server-side.

Step 3: The server checks the php script, and if it is correct, it redirects the client to the requested page.

Step 4: If the script is not matched, a plain Html output is sent back as a result.

An Example of PHP Programming

Let’s see a simple example of php printing “Hello World!” to the output screen.


In the above image, you can see we have used the “Echo” function inside the php script to print ‘Hello World!’ on the output screen. This is how php scripts are embedded inside the HTML language.
