1.) Serious bug, nesting of foreach() does not work if the nested foreach() works with a copy of the same var.
Code below results in...
"b0a0a1a2a3a4a5a6"
instead of "b0a0a1a2a3a4a5a6b1a0a2....b6a0a1a2a3a4a5a6" foreach() copies the array it uses to use the pointer internally, why doesn?t nesting work?
That?s a bug that will definitively affect users...


$b=$a=array(0,1,2,3,4,5,6);
foreach($b AS $test)	{
	print 'b'.$test;
	foreach ($a AS $test2)	{
		print 'a'.$test2; } }

2.) Once again this can be "fixed" using this strange snipplet:
$b=&$b; 
Which should BTW, (in my eyes) not work, because $b=&array(0,1,2,3,4,5,6) does not work too.
