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?

Answer 1

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
