Check the RegEx forums for examples.

preg_match is one way.

 

Javascript would be another, granted JS could be disabled.

if (preg_match('/[0-9]{4}-[0-9]{2}-[0-9]{2}/', $date)) {
// matched
}
else {
// no match
}

$date = '2009-04-22';

$parts = explode('-', $date);
if (count($parts) != 3 || !checkdate($parts[1], $parts[2], $parts[0])) {
echo 'Invalid';
}
else {
echo 'Valid';
}

 

Better than regex because it checks that it's actually a real date.
