Description:
------------
Suggestion:
Could you please implement a function to merge associative arrays without overwriting duplicate
keys.

Unless there already is one that I have missed?

I have provided a small example that works to a point that will demonstrate my idea.

Thanks. 

Test script:
---------------
function array_merge_assoc($array1, $array2){	
	foreach($array2 as $key => $value){
		if(array_key_exists($key, $array1)){
			$result[$key] = array_merge($array1[$key], $array2[$key]);
			unset($array2[$key]);
		}else{
			$result[$key] = $array2[$key];
		}
	}
	return $result;
}
$userConfig = ['libraries' => ['database', 'session',
'security']];
$defaults = ['libraries' => ['benchmark' , 'event',
'error'],
	   'helpers' => ['html','date','file']];
print_r(array_merge_assoc($userConfig,$defaults));

Expected result:
----------------
Array
(
    [libraries] => Array
        (
            [0] => database
            [1] => session
            [2] => security
            [3] => benchmark
            [4] => event
            [5] => error
        )

    [helpers] => Array
        (
            [0] => html
            [1] => date
            [2] => file
        )

)
