Re: [PHP] Question on functions

[Jason]

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...

$GLOBALS holds all variables defined in main(), main() meaning outside 
any function or class

//main()
$my_var = 'test';
function myFunction()
{
    echo $GLOBALS['my_var'];
    // is the same as:
    global $my_var
    echo $my_var;
    // 'global' just creates a local reference to the global variable
    // global $my_var; is the same as:
    $my_var =& $GLOBALS['my_var'];
    echo $my_var;
}
