Difference between GET and POST method?

Get methods are used to send data to the server.

(i) GET method data is sent through query string and display browser’s address field.

Example:-

$url="http://abc.com?email=john@abc.com&name=john"

Note:- in the above URL first query string add through ? mark after that add query string through & mark.

(ii) GET method is mostly used for submitting a small amount and less sensitive data.

You can get form fields value through $_GET[] array method.
Example:-

$get_email=$_GET['email'];

(i) POST method data is sent by standard input (nothing shown in browser’s address field).
(ii) POST method is mostly used for submitting a large amount or sensitive data.

You can get form fields value through $_POST[] array method.
Example:-

$post_email=$_POST['email'];
