I want to add +2 to an array elements without looping(foreach).

$arr=array(5,6,8,0,55,64,1);

wanted output:

$arr=array(7,8,10,2,57,66,3)

Then array_map is you friend :

function foo($n) { return($n + 2); }
$arr = array(5,6,8,0,55,64,1);
$ouput = array_map("foo", $arr);

EDIT after the answer of Gautam3164 : array_walk is also an option, indeed. Just dont forget that array_map returns a new array when array_walk takes a reference and updates your array.

Try this

array_walk($array, function(&$item) { $item += 2; });
