php - Merge Arrays, Sort Value, Remove Duplicates and Reindex -

i have 2 separate arrays

i want merge these arrays, can't seem this.

result f1

array (     [id] => array         (             [0] => 1             [1] => 2             [2] => 3         )  ) 

result f2

array (     [id] => array         (             [0] => 2             [1] => 7             [2] => 9         )  ) 

final result desired

array (     [id] => array         (             [0] => 1             [1] => 2             [2] => 3             [3] => 7             [4] => 9         )  ) 

note reindexing values numerical order.

many thanks

here's way without removing 'id' keys:

$newarray = array_merge_recursive($joinedids, $committeeids); $newarray = array_map(function($e){return array_unique($e);}, $newarray);
