How can I create an array from the values of another array's key?

Question

I have an array as follows:

$arr1 = array(
  0 => array(
    \'name\' => \'tom\',
    \'age\' => 22
  ),
  1 => array(
    \'name\' => \'nick\',
           


        

Answer 1

if you are using Laravel, then simply use array_pluck:

$arr2 = array_pluck($arr1 , 'name');
