I have a script that recieves a journal entry from a form... What is the code that converts a web address like http://www.frozenheat.net/ to <a href="http://www.frozenheat.net/>http://www.frozenheat.net/</a>? Of course these are in a string like $string that inculdes

"I have visited this one website http://www.frozenheat.net/ and i think it is good."

Please help...
