Question

Looking for a bit of regular expression help using PHP. What is the regex for the following:

EXACTLY {{file: THEN 24 characters from a-zA-Z0-9 THEN EXACTLY }}

Example:

{{file:504c2ee3ff558cb40700000b}}

Looking to match that pattern. Thanks much.

Try:

preg_match_all('/\{\{file:[a-zA-Z\d]{24}\}\}/', $str, $matches);
