Oh no, I think that´s the change Andi wanted to make. I personally do use array_keys() in foreach() too and did not know that that will be disallowed too. Andi told about "obscure" code... ...? Peter Kocks wrote:

No, no, no.... as the manual clearly states: foreach(array_expression as $value) statement since array_keys() returns an array, the code should work just fine. If it doesn't then the langauge has changed. Of course, this is a big problem for us as we have used the array_keys form all over the place in our code. --pk -----Original Message----- From: chrisv@b0rked.dhs.org [mailto:chrisv@b0rked.dhs.org] Sent: Saturday, August 12, 2000 12:55 PM To: Peter Kocks Cc: php-dev@lists.php.net Subject: Re: [PHP-DEV] foreach incompatibility
The following snippet of code works fine in php-4.0.1pl2, but not in the current CVS. I'm hoping this is a bug, and not an evolution of the language. <?
        $foo = array("a"=>"b", "c"=>"d", "e"=>"f");
        foreach (array_keys($foo) as $i) {
            echo "$i\n";
        }
?>
I'm not sure about that, but if I want the array keys, i'd personally use: $foo = array("a" => "b", "c" => "d", "e" => "f"); foreach ($foo as $i => $dummy) { echo "$i\n"; } Chris
