abs of an array

Question

Which is the easy way of getting the abs of an array in php? It has to be a better way. This works, but in multidimensional array it has some limitations

function make_abs($numbers) {
 $abs_array = array();

 foreach($numbers as $key=>$value)
   $abs_array[$key] = abs($value);

 return $abs_array;
}

Answer 1

Use a map function:

array_map("abs", $numbers)
