Re: Question on functions

[Jason <jason.gerfen@xxxxxxxxxxxx>]

Yeah the global stuff I understand and can use fine.  What I would like 
more information about is the use of arguments to functions i.e.
function( $user, $pass, $db ) {
 $db = @mysql_connect( $user, $pass, $db );
}

I understand parts but googling for the proper use of functions in php 
hasn't gotten me anywhere...
