php - How to extract particular fields from an array -

i have array looks

$articles = array([0] => array('title' => 'when ....',                                'description' => '....',                                 'created' => '2011-02-21'                               ),                    [1] => array('title' => 'something ....',                                'description' => 'when ....',                                 'created' => '2011-02-21'                               ),             ); 

i want extract titles. there anyway retrieve titles without using , foreach loops. dont mind title becomes single string. thinking implode array adds description , created.

you can use example array_map, why not want use loops? in fact every method, able modify array in way want it, iterate on it.

function reduce_to_title ($item) {   return $item['title']; }; $titles = array_map('reduce_to_title', $articles); 

or since php>=5.3

$titles = array_map(function ($item) {   return $item['title']; }, $articles);
