Can someone point me where the following behaviour is documented:

    $ php -q
    <?     $foo = array(27 => 'Ene');
    $bar = array(-1 => 'Mene');

        $baz = $foo + $bar;

    var_dump($baz);
    ?>
    array(2) {
      [27]=>
      string(3) "Ene"
      [-1]=>
      string(4) "Mene"
    }

cheers

I guess it's not. There is note explains this behavior. Accoding to the note, "PHP Developer's Cookbook claims (p. 87 and sort of on p. 108) that '+' is syntactic sugar for array_merge." -- Yasuo Ohgaki
