Note Submitter: ssadler at mashi dot org Reason: bad code ---- If you want to check the validity of an integer from user input, use this: <?php function get_int(&$i,$set=false) { if ($set) $j =& $i; else $j = $i; return ((string) $j === (string) $j = (int) $j); } ?> This is the most efficient way that I have found, it will return true on any string or integer variable containing a 32bit signed int. If $set is true, it will also cast the input to int type.
