[SOLVED] is_int

[The Little Guy]

Why does the is_int functions not work?

 

If $m, $d, $y contains a letter, Invalid Date is echoed out.

If $m, $d, $y doesn't contain a letter, Invalid Date is echoed out.

<?php
list($m,$d,$y) = explode("/",$_GET['date']);
if(strlen($m)<2||strlen($m)>2||strlen($d)<2||strlen($d)>2||strlen($y)<4||strlen($y)>4||_int($m)||!is_int($d)||!is_int($y)){
echo 'Invalid Date';
}
?>

Are leading zeros lost?

Sorry I was using the wrong function

 

I needed is_numeric()
