Is using array_flip and array_combine the most efficient method to separate attributes and values in PHP?

When separating attributes and values in PHP, using array_flip and array_combine can be an efficient method. First, flip the array to make the values the keys, then combine the flipped array with the original array to separate attributes and values. 

// Original array with attributes and values
$data = array('name' => 'John', 'age' => 30, 'city' => 'New York');

// Flip the array to make values the keys
$flipped = array_flip($data);

// Combine the flipped array with the original array to separate attributes and values
$attributes = array_diff_key($data, $flipped);
$values = array_diff_key($data, $attributes);

// Output separated attributes and values
print_r($attributes);
print_r($values);
