Syntax
array_column(array, column_key, index_key)
Parameter Values
Parameter	Description
array	Required. Specifies the multi-dimensional array (record-set) to use. As of PHP 7.0, this can also be an array of objects.
column_key	Required. An integer key or a string key name of the column of values to return. This parameter can also be NULL to return complete arrays (useful together with index_key to re-index the array)
index_key	Optional. The column to use as the index/keys for the returned array

<?php
// An array that represents a possible record set returned from a database
$a = array(
  array(
    'id' => 5698,
    'first_name' => 'Peter',
    'last_name' => 'Griffin',
  ),
  array(
    'id' => 4767,
    'first_name' => 'Ben',
    'last_name' => 'Smith',
  ),
  array(
    'id' => 3809,
    'first_name' => 'Joe',
    'last_name' => 'Doe',
  )
);

$last_names = array_column($a, 'last_name', 'id');
print_r($last_names);
?>

Output:

  [5698] => Griffin
  [4767] => Smith
