note 32830 modified in function.fsockopen by danbrown

Here's a quick function to establish a connection to a web server that will time out if the connection is lost after a user definable amount of time or if the server can't be reached. Also supports Basic authentication if a username/password is specified. Any improvements or criticisms, please email me! :-) Returns either a resource ID, an error code or 0 if the server can't be reached at all. Returns -1 in the event that something really wierd happens like a non-standard http response or something. Hope it helps someone.
