[RESOLVED] date field validation

[thread_PHP]

hi all
i have a date displaying in the following format
29-11-2007
i want to calculate expiry date for the above date ie., 30 days to the above date how can i do it please help me

[NogDog]

$date = '29-11-2007';
$expires = strtotime("$date + 30 days");
echo date('d-m-Y', $expires); // outputs '29-12-2007'

Thank you NogDog. If i want to check the expiry date is greater than todays date then i should close the session how can i do this

[NogDog]

You could just compare $expires to time() (both are "UNIX time" in seconds).

if(time() > $expires)
{
   // it is now 30 days or more past the expiration date
}
