Warning: preg_match() [function.preg-match]: Unknown modifier '/' -- I would like help to fix this problem.

Question

I'm trying to use preg_match to return all the URL's that are inclosed in " " in a page source code.

The code I am using is

preg_match('"http://(.+?)\"', $code, $matches);

And I am getting the following error:

Warning: preg_match() [function.preg-match]: Unknown modifier '/' in .... on line 13

Please help me. This is driving me mad!

Thank you.

Answer 1

preg_match('~"http://(.*)"~iU', $code, $matches);

Your issue was you need delimiters (I chose ~) to use with the pattern. See the preg_match() man page for more information.
