even better, verify the date as a whole rather then just as an int.
<?php
$time = mktime(0, 0, 0, $month, $day, $year);
$date = getdate($time);
$month = $date['mon'];
$day = $date['mday'];
$year = $date['year'];
?>
there you go, try it. someone puts an invalid date in? no problem it fixes it for you.

Hi
I am trying to validate a form to check the user has entered there date of
birth correctly
There are three fields day, month & year.
how can I check whether a string is a number?
I have tried using is_long(), is_int(), is_integer() to check the values
,but it doesn't seem to be working.
the code I have tried is
if(!is_int($dobd))
{
print "error";
}
else
{
//carry on
}
could someone help me as to where I'm going wrong
TIA
