Question

I have two arrays:

$a = array([0]=>1 [1]=>2 [2]=>3);
$b = array([0]=>a [1]=>b [2]=>c);

I want to merge them like

$ab=array( [a]=>array([0]=>1 [1]=>2 [2]=>3) 
           [b]=>array([0]=>a [1]=>b [2]=>c)  );

How to do this ?

I tried array_merge() but it does not work as I want it to.

Answer 1

In this case you can just go:

$ab = array('a' => $a, 'b' => $b);
