PHP Require Once Statement
What is Require Once statement?
Explanation
The "require_once()" Statement is similar to "require()" except that it will check if the file has already been included and if so, will not include it again.
Example<?php
include 'test1.php';
require_once ("test1.php");
?>
In the above example the since test1.php is already included, "require_once" statement will give a Fatal Error message
