How can I find and replace all URL's using regular expressions in PHP?

Question

My URL's might not be well formatted, so it could be http://www.google.com/ or www.google.com or google.com and it'll be in a block of text like:

This is google.com and it rocks!

I need to find the website and replace it with [*********]

Any ideas?
