php grab http or www links from text and return full url

Interesting. Is this free text uncontrolled? My point is this: you need to determine what rules you'll use as delimiters for your search whether that's via regex or strstr() or whatever.

For example I can easily grab your example string:

www.functionplace.com?id=1324354

but miss your requirement totally for something like:

http://functionplace.com?id=1324354&rabbit=jumpedOutOfAHat

Just a thought,
