Answer 1

Hey all my commenting people were right... i don't know why it happened but when i restarted my xampp it worked fine for me :)

So this is 100% correct

index.php

<?php
require_once('fr.php');
header('Location:'.abspath().directory());
?>

fr.php

<?php
require_once('functions.php');
?>

functions.php

function abspath()
{
return $_SERVER['DOCUMENT_ROOT'];
}
