- Support static members. The following script works:

Browse source 
<?
	class foo
	{
		class bar
		{
			function init_values()
			{
				for ($i=1; $i<10; $i++) {
					foo::bar::$hello[$i] = $i*$i;
				}
			}

			function print_values()
			{
				for ($i=1; $i<10; $i++) {
					print foo::bar::$hello[$i] . "\n";
				}
			}
		}
	}

	foo::bar::init_values();
	foo::bar::print_values();

	for ($i=1; $i<10; $i++) {
		print $hello[$i]?"Shouldn't be printed\n":"";
	}
?>
