PHP-正则表达式来查找[digit] [digit] [colon] [digit] [digit]

Question

I'm attempting to extract [digit][digit][colon][digit][digit] from a string if it is present. The Regex should match:

02:59
03:24

So far I've got quite lost, though I've realised \\d will return me a single digit, and \\d{2} should find me 2, but I've got stuck with adding in the separator : and finding 2 more digits to fit into my preg_match :

$trackTime = preg_match($regexEludingMe, $track, $matches);

Example $track is: 10. Break Your Heart 03:42 should match 03:42

Answer 1

Just add the separator : and duplicate the first part that you've already figured out \\d{2}:\\d{2} . Don't forget delimiters:

 preg_match('/\d{2}:\d{2}/', $track, $trackTime);

 print_r($trackTime);
