PHP: Can I get the index in an array_map function?

Question

I\'m using a map in php like so:

function func($v) {
    return $v * 2;
}

$values = array(4, 6, 3);
$mapped = array_map(func, $values);
var_dump($mapped);
         


        

Answer 1

You can create your own map function using foreach:

$val) {
        $result[$key] = $callback($key, $val);
    }
    return $result;
}

$values = array(4, 6, 3);
$mapped = foreachMap('myCallback', $values);
var_dump($mapped);
