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

Question

I have an array of arrays, with the following structure :

array(array(\'page\' => \'page1\', \'name\' => \'pagename1\')
      array(\'page\' => \'pa

Here's a functional way of doing it:

$data = array(
            array('page' => 'page1', 'name' => 'pagename1'),
            array('page' => 'page2', 'name' => 'pagename2'),
            array('page' => 'page3', 'name' => 'pagename3'));

$result = array_map(create_function('$arr', 'return $arr["name"];'), $data);
print_r($result);
