# include_once

(PHP 4, PHP 5, PHP 7)
Examples:
include_once with a case insensitive OS in PHP 4

With PHP 4, _once functionality differs with case-insensitive operating systems (like Windows) so for example:

<?php
include_once "a.php"; // this will include a.php
include_once "A.php"; // this will include a.php again! (PHP 4 only)
?>
