Implementing GtkTreeModel

[Matt-239]

Ok, so I'm trying to create my own class implementing GtkTreeModel to
make it much faster when dealing with thousands of rows. The problem I
have is there is a method called "foreach" that makes PHP blow a gasket
when I try to define it.

class TestTreeModel implements GtkTreeModel
{
        public function foreach($callback_func)
        {
                // do stuff
        }

        // all the other abstract methods are defined properly
}

This will return:

Parse error: syntax error, unexpected T_FOREACH, expecting T_STRING in
foo.php on line xx

Any idea on how to get around this? Thanks!

-Matt

Matt,

I'm not aware of a way to define a function named foreach since that's
a reserved word in PHP.  However, I find the idea of reimplementing
the GtkTreeModel functions (written in C) in PHP for speed extremely
questionable.  If you could elaborate on when you observe a speed
problem and how you intended to correct it PHP-side then I or others
might be able to offer better advice.

This is actually a bug in the php-gtk implementation and in the next
release (which should have cairo support as well) the functions that
conflict with php reserved words (foreach will be for_each, there are a
few others) will be renamed appropriately.  Until then, unfortunately
you're out of luck ;)

Thanks,
Elizabeth
