PHP regex to match various hh:mm:ss video durations

Question

I can't get a regex match when there is an hour value given. How can I get a possible hour to match (with or without leading zero)?

$val = '01:04:06'; // doesn't match
$val = '1:04:06'; // doesn't match
$val = '04:06'; // matches
$val = '4:06'; // matches

preg_match("/^([\d]{1,2})\:([\d]{2})$/", $val, $matches);

Try: `/^(\d{1,2}):\d{1,2}(?:\d{1,2})?$/` – anubhava Feb 24 '17 at 18:53 — anubhava, Feb 24 '17 at 18:53

Just remove the leading ^

You can rewrite your regex as /(\d?\d):(\d?\d)$/ if you want minutes and seconds.

If you want (optionally) the hour, write /((\d?\d):)?(\d?\d):(\d?\d)$/ instead.

You forgot the « $ » in your test. – Mid' Feb 24 '17 at 19:01

If you want to match it as a whole, just make a group for the first sequence until :, and added a quantifier, so it could happen 1 or 2 times.

/^(([\d]{1,2})\:){1,2}([\d]{2})$/

Test it here

Here is another one from a similar stackoverflow post but converted for preg_match:

preg_match("/^(?:(?:([01]?\d|2[0-3]):)?([0-5]?\d):)?([0-5]?\d)$/", $val, $matches);
