Was unable to open sanitize.php file due to spelling mistake

init.php

<?php

//start the session
session_start();

//$GLOBALS['config'] will read the config.php class
$GLOBALS['config'] = array(
	'mysql' => array(
		'host' => '127.0.0.1',
		'username' => 'root',
		'password' => 'Founder2013',
		'db' => 'spoqe'
	),
	'remember' => array(
		//Name of the cookie.
		'cookie_name' => 'hash',
		// Time for a cookie to expiry.
		'cookie_expiry' => 604800

	),
	'session' => array(
		//When the session start it will give a session name of user.
		'session_name' => 'user'
	
	)
);

//Auto reading all the classes in the cleasses folder.
spl_autoload_register(function($class) {
	require_once 'classes/'.$class.'.php';
});

// added the functions
require_once 'functions/sanitize.php';

?>
