Creating a link from users url post.

[quasi]

Is there perhaps a nice php function that can parse through a text string and identify any url strings and create a new string with the html link code?

I'm allowing users to post events and I want to be able have any urls they add to their event description be a link when they are displayed.

AFAIK there is no specific function to do that. It can be done with pattern matching using regular expressions. There are some examples in the comments on [php.net...]
