OK, basic question, but one that's foxing me.
I need to validate a field that can validate if an inputted URL is in a correct format, butthe more i think about it the more url formats I come up with, eg.
http://www.xxxxx
http://www3.xxxxx
https://www.xxxxxx
https://www3.xxxxxx
http://xxxxxx
https://xxxxx
ip addresses
Any ideas or solutions very welcome.

Well, regex is probably the best answer. Keep in mind that the more idiot proof you try to make this regex, the more likely it is that someone will become a better idiot and insert something invalid that slips though. That said... :-)
print eregi("^http[s]?://[[:alnum:][:punct:]]+",$url);
should get you started.
It's not perfect, it needs to exclude - from the hostname, and check for a slash on the end etc...
Cheer mate, you're a star.
