Custom 404 Error Pages

[Jick]

I need a php script that will allow me to have my own 404 errors and what not. I want it so when a page isn't found or something it will show my error page instead of the servers error page. Is there a script to do this? Also is there a list of all the possible server errors a site would display so I could make a page for each error. If someone could help me I would greatly appreciate it. Thanks so much.

I think that you will need to use a .htaccess file to do that... Not 100% sure, though.

Yeah this is done in the server config files.
