PHP 4.0 Bug #5052: Bug in ref-count(?) working with nested foreach() on copied var

From: waldschrott@kiffen.de Operating system: win2000 / perhaps all PHP version: 4.0 Latest CVS (15/06/2000) PHP Bug Type: Feature/Change Request Bug description: Bug in ref-count(?) working with nested foreach() on copied var 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.
