You might use 2 capturing groups and make use of \K to not match the first part of the url to get the desired matches.

https?://.*/\K([^#\s]+)#(\S+)

• https?:// Match the protocol with optional s, then ://
• .*/ Match until the last occurrence of /
• \K Forget what is matched until here
• ([^#\s]+) Capture group 1 , match 1+ occurrences of any char except a # or whitespace char
• # Match the #
• (\S+) Capture group 2 , match 1+ occurrences of a non whitespace char

$url = "https://test.com/file/5gdxyYpb#_FWRc4T12baPrppZIwVQ5i18Sq16f7TXU82LJwY_BjE";
$pattern = "~https?://.*/\K([^#]+)#(.*)~";
$res = preg_match($pattern, $url, $matches);
