wp_list_pluck ( $list, $field, $index_key = null )

Parameters:

(array) $list List of objects or arrays
(int|string) $field Field from the object to place instead of the entire object
(int|string) $index_key Optional. Field from the object to use as keys for the new array. Default null.

Change Log:

Pluck a certain field out of each object in a list.

This has the same functionality and prototype of array_column() (PHP 5.5) but also supports objects.
