Is there a function to extract a ‘column’ from an array in PHP?

by

As of PHP 5.5 you can use array_column():

<?php
$samples=array(
            array('page' => 'page1', 'name' => 'pagename1'),
            array('page' => 'page2', 'name' => 'pagename2'),
            array('page' => 'page3', 'name' => 'pagename3')
            );
$names = array_column($samples, 'name');
print_r($names);
