Note Submitter: kristopolous at yahoo dot com ---- I constantly forget the direction of array_merge so this is partially for me and partially for people like me. array_merge is a non-referential non-inplace right-reduction. For different ctrl-f typers, it's reduce-right, side-effect free, idempotent, and non in-place. ex: $a = array_merge(['k' => 'a'], ['k' => 'b']) => ['k' => 'b'] array_merge(['z' => 1], $a) => does not modify $a but returns ['k' => 'b', 'z' => 1]; Hopefully this helps people that constant look this up such as myself.
