php - Better way to unset multiple array elements

Question

The deal here is that I have an array with 17 elements. I want to get the elements I need for a certain time and remove them permanently from the array.

Here's the code:

$name = $post['name'];
$email = $post['email'];
$address = $post['address'];
$telephone = $post['telephone'];
$country = $post['country'];

unset($post['name']);
unset($post['email']);
unset($post['address']);
unset($post['telephone']);
unset($post['country']);

Yes the code is ugly, no need to bash. How do I make this look better?

Answer 1

Use array_diff_key to remove

$remove = ['telephone', 'country'];

array_diff_key($post, array_flip($remove));

You could use array_intersect_key if you wanted to supply an array of keys to keep.
