Convert Array of Objecta to single array using only the value

Question

How can I convert and object like this:

Array(
   Object(
       'id' => 1
   ),
   Object(
       'id' => 2
   ),
   Object(
       'id' => 3
   ),
)

To and array like this:

Array(1,2,3)

Without using a for loop. Is there some pre-built function in php to accomplish that?

The built in function in PHP is array_column

$ids = array_column($array, 'id');

It will fetch all ids from the inner objects/associative arrays and put them in a unidimensional array.

$ids = [1, 2, 3];
