PHP: Merge array by defining parent array only?

Question

Is it possible to do this in PHP:

$a['foo'] = [1,2,3];
$a['bar'] = [4,5,6];

Instead of array_merge($a['foo'], $a['bar']), you would use simply use something like array_merge($a) instead?

You mean like what array_merge_recursive() does? (it would have been helpful if you had provided an example of your expected output). — symcbean, Feb 04 '16 at 16:56
