It is essential rather mandatory for you to know the importance of PHP and AJAX in the field of web development.

What is PHP?
The full form of PHP is PHP: Hypertext Preprocessor. It is basically a server-side scripting language which is designed for web development. In 1995 Rasmus Lerdorf took the initiative to create this general purpose programming language. PHP is an open-source and free software which can be easily installed on millions and billions of websites for enhancing the operating system of web servers. An example of the function of PHP is described below:

function myFunction() // defines a function, this one is named "myFunction"
return ‘Sketch Web Solutions’; // returns the value ‘Sketch Web Solutions ‘

echo myFunction() . ‘!’; //outputs the text concatenated with the return value of myFunction.

// myFunction() is called as the result of this syntax.
// The result of the output will be ‘Sketch Web Solutions!’


What is AJAX?
AJAX stands for Asynchronous JavaScript and XML and knowing JavaScript & DOM (Document Object Model) is a ‘must’ for using AJAX. It is considered as a group of web development technologies which were developed in the year 1990. Sending and retrieving data to and from a server and creating asynchronous web applications are possible with the innovation of AJAX. Its uniqueness lies in its capability of reducing the task of refreshing a page which is reloaded for every user interaction. Here follows an example of the function of AJAX:

// This is the client-side script

// Initialize the Ajax request
var xhr = new XMLHttpRequest();
xhr.open(‘get’, ‘send-ajax-data.php’);

// Track the state changes of the request
xhr.onreadystatechange = function(){
// Ready state 4 means the request is done
if(xhr.readyState === 4){
// 200 is a successful return
if(xhr.status === 200){
alert(xhr.responseText); // ‘This is the returned text.’
alert(‘Error: ‘+xhr.status); // An error occurred during the request

// Send the request to send-ajax-data.php
