empty value checks for array_column

Question

From the following array I can pull the last names by using array_column built in function of PHP. Now, My question is- Can I pull data if last_name is not empty?

$a = array(
  array(
    'id' => 5698,
    'first_name' => 'Peter',
    'last_name' => 'Griffin',
  ),
  array(
    'id' => 4767,
    'first_name' => 'Ben',
    'last_name' => ''
  )
);

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

That means My output will be Griffin.

You can easily do it by array_diff

<?php
$a = array(
  array(
    'id' => 5698,
    'first_name' => 'Peter',
    'last_name' => 'Griffin',
  ),
  array(
    'id' => 4767,
    'first_name' => 'Ben',
    'last_name' => ''
  )
);

$last_names = array_diff(array_column($a, 'last_name'),['']);
print_r($last_names);
?>
