php - Remove duplicates from multidimensional array sub key -
i trying make php array unique. looks this:
.... [7] => array ( [extensions] => array ( [empty cart] => array ( [title] => title [name] => cwp_emtpy_cart_title [type] => input [default] => might interested in: [help] => ) ) ) [8] => array ( [extensions] => array ( [idea vote] => array ( [title] => must logged in vote [name] => cwp_idea_logged_in [type] => dropdown [options] => array ( [0] => yes (default) [1] => no ) [default] => 0 [help] => ) ) )
i want combine 2 array keys name "extensions". trying get:
[7] => array ( [extensions] => array ( [idea vote] => array ( [title] => must logged in vote [name] => cwp_idea_logged_in [type] => dropdown [options] => array ( [0] => yes (default) [1] => no ) [default] => 0 [help] => ) ) array ( [empty cart] => array ( [title] => title [name] => cwp_emtpy_cart_title [type] => input [default] => might interested in: [help] => ) ) )
when array created tried using:
array_unique
as as:
array_map('unserialize', array_unique(array_map('serialize', $commercewp_settings_array)));
however neither has effect @ all.
