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 - Markus

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."

Also, there have been discussions on Dev about this issue before. Might be a bit tough to find though. :)

    Hmm .. well, at least, it should be clearly documented.

I think it should be documented, unless "+" is going to be depreciated. (I hope it's not ;) -- Yasuo Ohgaki
