map function to loop through multiple arrays in parallel

[sujancse]

It will work like list comprehension in Elixir, Python

Usage Example

$array1 = array(1,2,3);
$array2 = array(4,5,6);

$data = map(function($item1, $item2) {
	    return $item1 * $item2;
}, $array1, $array2);

// [4,10,18]

The helper can take variable number of arrays.
