Reason: bad code

To expand on the above points, ctype_digit returns false for all integer values below 256, and true
for those above:
<?
echo ctype_digit(256) ? 'true' : 'false'; // true
echo ctype_digit("256") ? 'true' : 'false'; // false
echo ctype_digit(255) ? 'true' : 'false'; // true
echo ctype_digit("255") ? 'true' : 'false'; // false
?>
