add info to end of link

[leena]

Hello everyone,

I need to search some text (submitted by a user) for all URL's within the text. Then I want to add some info to the URL. I have been searching on how to do this, and so far I can't find the information I need.

If there is a link in the text submitted by the user I need to add "&adminID=12".

I was trying to think of how explode and split might help me, but I don't think that can work because there could be multiple links in the text, and the links can be anywhere in the document. Also the a href tag could have double or single quotes, or have targets etc.

Anyways I was looking up parsing. There seems to be many types, but I need one that will get my URL from my link.

I've never used parsing before so i'm not sure what I need to do, or if that is even the right direction for me to go in.

Thanks for your time. Any help is greatly appreciated.

The answer to almost all string parsing is REGEX. Regular Expressions are well documented and definately worth the effort of learning a little about.

PHP provides a couple sets of regex functions including perl compatible regex ([man]preg_match[/man], [man]preg_replace[/man]). The syntax is a little strange but straight forward and the documentation has plenty of examples for you.
