Re: [PHP-GTK] Strange result

So you're trying to develop an array of objects that you can access via a 
loop, no? Here's what I've done that I think is similar, and seems to work 
pretty well. 

Nicely, by keeping object references in an array, you can globalize the array 
even though a global variable is itself a reference. So you end up with a 
referenced array of references. 

<?

Function hideThemAll()
	{
	global $objs;
	foreach($objs AS $obj)
		$obj->Hide();
	return true;
	}

$objs=array();
$objs[]=&New GtkWidget();
$objs[]=&New GtkWidget();

foreach($objs AS $obj)
	{
	$obj->doSomeMethod();
	}

hideThemAll(); 

?>

I hope this helps - works for me well in a large codebase.
