finding links in a web page
Hi
I have been looking for a function that finds links on a web page, i have used get_meta_tags() and file_get_contents() to get data off of a web page and wondered if there was something similar to get URLs. If not what would be simple and logical way to get URLs off a page?

Re: finding links in a web page
I'm attempting to write some crawling script, i want to extract and store in MySql all URLs encountered on a web page and then open the file that they point to and repeat the process for a nominal amount of web pages.

Re: finding links in a web page
Regular expressions.
Start here: http://en.wikipedia.org/wiki/Regular_expression Perhaps try these tutorials: http://www.regular-expressions.info/ Then go hardcore: http://www.regexlib.com/ (only when you know your regexps) That should get you started, but don't ask me how to run a regular expression in PHP... I don't know! [EDITED] Here you go: http://www.regular-expressions.info/php.html http://weblogtoolscollection.com/regex/regex.php LOL
