Access value in PHP array with unknown dimensions -

consider multidimensional array following structure:

[a] => array         (             [b] => array                 (                     [c] => array                         (                             [value] => 0                             [other_value] => 1                         )                  )          ) 

i want access $array[a][b][c][value], value @ $array[a][b][c][d][value].

i'm not entirely how describe i'm trying do. think alternative explanation be: want access each element in $array[a][b][c] able access each element in $array[a][b][c][d], etc., using foreach, unknown number of nested arrays.

array_walk_recursive() come in handy here.

array_walk_recursive($array, function($val, $key) {     if ($key == "value") {         //     } });
