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);
Is it possible to get the index of the value in the function?
Also - if I'm writing code that needs the index, should I be using a for loop instead of a map?
