Capturing a pattern of unknown repitition in PCRE

Question

This may be a quick question for experienced regular expressionists, but I\'m having trouble getting my match to execute correctly.

Suppose I had a string that looke

Answer 1

No, it is not possible to match an unknown number of capture groups.

If you try to repeat a capture group, it will always contain the last value captured.

Could you explain a bit more broadly what you're trying to do? Perhaps there is another simple way to do it (possibly without regular expressions).

Answer 2

If you want the items in the subdomain, and then all matches between the dashes... This should work:

$string = "http://aaa-bbbb-cc-ffffffffd-eee-.sub.dom";

preg_match("/^http:\/\/([\w-]+?)\..*$/i", $string, $match);

$parts = explode('-', $match[1]);

print_r($parts);

Short of that you will probably have to build a small parsing script to parse the string yourself if that doesn't do it for you.
