asphp has done a great job and that one of Markus P. N. is also good too.
However i made my own more concise version of the asphp code that supports different lenght strings
and i used the same tests of Markus in order see how it works.
<?php
if(!function_exists('hash_equals')) {
function hash_equals($known_string, $user_string) {
$ret = 0;
if (strlen($known_string) !== strlen($user_string)) {
$user_string = $known_string;
$ret = 1;
}
$res = $known_string ^ $user_string;
for ($i = strlen($res) - 1; $i >= 0; --$i) {
$ret |= ord($res[$i]);
}
return !$ret;
}
}
?>
