Bug description:  ctype_digit not validating int values

Description:
------------
When passing an integer to ctype_digit, it will fail validating it. I
tested several times, looks like this behaviour is consistent, I also tried
using ctype_digit(65) which will also return "false".

The PHP version is actually 5.1.6, running on Fedora 6 x86_64 with Apache
2.2.6 , all installed from the Fedora Repository.

Same behaviour successfully reproduced with PHP 5.2.5 + Apache 2.0.54 on
Suse9 x86_64.

Possibly somewhere when the parameter passed is cast to a string, the
value is somehow corrupted.

Reproduce code:
---------------
function getm($width, $height) {
        $errors = array();
        if (!ctype_digit($width) || (int)$width <=0 ) {
                $errors[] = 'Width must be a positive integer value, ' . 
gettype($width)
. ' passed';
        }
        
        if (!ctype_digit($height) || (int)$height<=0 ) {
                $errors[] = 'Height must be a positive integer value, ' .
gettype($height) . ' passed';
        }
        
        return $errors;
}


$a = getm(48, 65);

var_dump($a);

Expected result:
----------------
array (0) {}

Actual result:
--------------
array(1) {
  [0]=>
  string(55) "Height must be a positive integer value, integer passed"
}
