php check for a valid date, weird date conversions

Question

Is there a way to check to see if a date/time is valid you would think these would be easy to check:

$date = \'0000-00-00\';
$time = \'00:00:00\';
$dateTime          


        

Answer 1

= strtotime($valid_date) ? true : false;
}

echo is_valid_date("00-00-00") ? 1 : 0;    // return 0

echo is_valid_date("3/5/2011") ? 1 : 0;    // return 1
