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.

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