this i due to the autoconversation of variables in PHP. Your string is converted into an integer during the comparison.The integer is 0, since no fitting value can be found.
So 0 equals 0.

<?php
        $i = 0;
        $s = 'the string';
        if($i == $s) {
                echo "'$s' == $i";
        } else {
                echo "'$s' != $i";
        }
?>
// This outputs 'the string' == 0
