date format

[SpeedShrew]

Hi all,
am new to this so stick with me.
Whats the best way of vaildating a date box in the format dd-mm-yyyy? without using mysql?
Also, how do I varify that Jon Doe is over 18?
Thanks.

list($day, $month, $year) = explode('-', $date);
if(checkdate($month, $day, $year))
{
   $date = mktime(0, 0, 0, $month, $day, $year);
   if($date <= strtotime('-18 years'))
   {
      // is 18 years old
   }
   else
   {
      // is NOT 18 years old
   }
}
else
{
   // invalid date was entered
}

Thanks, but could you explain it?

I could, but the manual explains it much better:
[man]list[/man]
[man]explode[/man]
[man]checkdate[/man]
[man]mktime[/man]
[man]strtotime[/man]
