RE: [PHP] Regex Help for URL's [ANSWER]
In case any one is looking for a solution to a similar problem as me, here is the answer. I used the code from my original post as my guiding light, and with some experimentation, I figured it out. To get any URL, regardless of where it is located, use this: preg_match_all(#\'http://(.*)\'#U, $content, $matches); This match anything similar to: 'http://www.domain.com/dir/dir/file.txt?query=blah' This is useful, if for example, you have a tag like this one: A HREF=javascript:void(0); ONCLICK=javascript:window.open = 'http://www.domain.com/dir/dir/file.txt?query=blah'; Now, for tags which are in quotes, rather than single quotes, just use: preg_match_all(#\http://(.*)\#U, $content, $matches); This is really only the first step. In order to be useful, you need a way to process these urls according to your own specific needs: preg_match_all(#\'http://(.*)\'#U, $content, $matches); $content = preg_replace(#\'http://(.*)\'#U, '###URL###', $content); This will modify the $content variable to change all urls to ###URL### You can then go through them one at a time to process them: for ($count = 0; $count count($matches[1]); $count++) -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Plus, http could be IN CAPS, so change the U to iU And, actually, SOME old-school HTML pages will have neither ' nor around the URL, and are (or were) valid: href=page2.html was considered valid for HTML for a long long long time So toss in (\|')? And then you may be finding URLs that are not actually linked but are part of the visible content, so maybe you only want the ones that have a[^]href= in front of them. If I can toss off 3 problems without even trying... So I still think Google or searching the archives (as I suggested off-list) will be the quickest route to a CORRECT answer, but here we are again in this same thread we've been in every month or so for the better part of a decade... PS the (\|') bit may move the URLs into $matches[2] instead of $matches[1] or whatever. -- Like Music? http://l-i-e.com/artists.htm -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

RE: [PHP] Regex Help for URL's [ANSWER]
In my opinion, it is the most reasonable solution. I have looked all over the web for something else, but this works perfectly for me. It's impossible to tell where an url starts and ends if you don't have it in quotes or single quotes. If someone really needs to find all the urls in a page, then they'll code their pages to make use of this limitation. -Original Message- From: Chrome [mailto:[EMAIL PROTECTED] Sent: Tuesday, May 16, 2006 8:24 PM To: 'Robert Samuel White'; php-general@lists.php.net Subject: RE: [PHP] Regex Help for URL's [ANSWER] -Original Message- From: Robert Samuel White [mailto:[EMAIL PROTECTED] Sent: 17 May 2006 01:16 To: php-general@lists.php.net Subject: RE: [PHP] Regex Help for URL's [ANSWER] All pages used by my content management system must be in a valid format.
