php - Make a simple array from a complex array -

-

i have array ($query) database:

array ( [0] => array     (         [category] => mercedes     )  [1] => array     (         [category] => bmw     )  [2] => array     (         [category] => bentley     )  )

i want make array $category:

array (     [0] => mercedes     [1] => bmw     [2] => bentley )

i tried array_merge() result doesn't want.

you have iterate on array, pick each 'category' value. 

foreach ($query $array) {     $newarray[] = $array['category']; }

$newarray contain values require.
