PHP - Move element in array to second position

Question

I have simple array from Wordpress manage_posts_columns filter, to change the columns in custom post type admin. The array looks like

$columns = array ('lastname' => 'Lastname', 'firstname' => 'Firstname', 'city' => 'City' );

and I'm adding ID column

$columns['id'] = 'ID';

I would need to move the id element to second position in the array. How can this be done?

The columns in Wordpress admin are displayed in the order of the array elements - and I need the ID column to be in second position. — user1049961, Mar 19 '14 at 15:09

Instead, you can use array_unshift to prepend elements onto an array, or array_push to add an element at the end of the array.

To reorder the associative array, you can use array_splice. A good example is here: http://uk.php.net/manual/en/function.array-splice.php#92651
