$foo = ['a' => 1, 'b' => 2, 'c' => 3]; $bar = ['c' => 4, 'd' => 5, 'e' => 6, ...$foo]; // is identical to writing $bar = ['a' => 1, 'b' => 2, 'c' => 3, 'c' => 4, 'd' => 5, 'e' => 6]; http://3v4l.org/inqtg#v540 In other words, in that scenario it's basically syntactic sugar to avoid having to write out the "body" of the array twice, and would behave identically as if you had done this. Of course, if the majority opinion that this is not the correct approach, I'm happy to admit I'm wrong :-) -- > PHP Internals - PHP Runtime Development Mailing List > To unsubscribe, visit: http://www.php.net/unsub.php > >
