PHP extract values from multidimensional array without a loop -

i'm wondering if it's possible extract values array, in php, without having loop through. here's part of array know mean;

array ( [0] => array     (         [0] => 76         [1] => adventures of huckleberry finn     )  [1] => array     (         [0] => 65         [1] => adventures of huckleberry finn     )  [2] => array     (         [0] => 59         [1] => bookcases     ) ) 

i'm after integer [0] each array - there function can quicker foreach loop (the way this) ?

thanks.

you looking array_walk()

$newarray = array(); $mycallback = function($key) use(&$newarray){   $newarray[] = $key[0]; };  array_walk($myarray, $mycallback); 

this of course if had array above in variable $myarray
