PHP's array_map including keys

Question

Is there a way of doing something like this:

$test_array = array(\"first_key\" => \"first_value\", 
                    \"second_key\" => \"second_valu         


        

Answer 1

I made this function, based on eis's answer:

function array_map_($callback, $arr) {
    if (!is_callable($callback))
        return $arr;

    $result = array_walk($arr, function(&$value, $key) use ($callback) {
        $value = call_user_func($callback, $key, $value);
    });

    if (!$result)
        return false;

    return $arr;
}

Example:

$test_array = array("first_key" => "first_value", 
                "second_key" => "second_value");

var_dump(array_map_(function($key, $value){
    return $key . " loves " . $value;
}, $arr));

Output:

array (
  'first_key' => 'first_key loves first_value,
  'second_key' => 'second_key loves second_value',
)

Off course, you can use array_values to return exactly what OP wants.

array_values(array_map_(function($key, $value){
    return $key . " loves " . $value;
}, $test_array))
