preg_match to parse a post ID

[wuwei101]

hello,

Here's the code I have:

[code]if (! PEAR::isError($req->sendRequest())) {
                if (preg_match('/edg176\/(\d+)/', $req->getResponseBody(), $matches)) {
                        $xangaPostID = $matches[1];[/code]

I am trying to parse the post ID number from my xanga page.  I am not sure why the (\d+) isn't working , since the post ID is simply everything after the edg176/.

The whole url usually looks like this:  http://www.xanga.com/edg176/nnn/xxx.html

I'm trying to get the nnn out of the posts.

Thanks

That should work, but you want to use preg_match_all() to get all the values and then reference them like $matches[1][0], $matches[1][1], $matches[1][2], etc.

Thanks.  I've read the documentation in the php manual for preg_match_all and I'm confused about what the set of 2 flags means.
