I was wondering what the general rule on using the global driective versus
passing in a variable by reference, why you should or shouldn't, etc.
e.g.
function ()
{
global $db;
$res =& $db->query( "SQL");
}
or
function ( &$db )
{
$res =& $db->query( "SQL");
}
or
function foo ()
{
$db = & $GLOBALS['database'];
$res = & $db->query();
}
or
function foo ()
{
$res = & $GLOBALS['database']->query();
}
Just some more possibilities...
cheers
