Count multidimensional array in php

Question

i need to count a multidimensional array, but with some rules.

My array is this:

<?$array[$iddom][$idrisp][$idopt][$iddoc][$idut]=$text;?>

and i have for example this values:

[1][1][0][0][31248]=
[1][1][0][0][46619]=
[2][4][0][0][31248]=
[2][5][0][0][46619]=
[3][6][1][0][31248]=
[3][6][3][0][46619]=
[3][7][3][0][31248]=
[3][7][2][0][46619]=
[3][8][1][0][31248]=
[3][8][1][0][46619]=
[4][9][0][0][46619]=
[4][11][0][0][31248]=
[5][13][5][0][31248]=
[5][13][6][0][46619]=
[5][14][4][0][31248]=
[5][14][4][0][46619]=
[5][15][6][0][31248]=
[5][15][5][0][46619]=
[6][0][7][6][31248]=
[6][0][7][6][46619]=

if i want to count only a part of array, i use this code:

<?$count=array_sum(array_map("count", $array[$key]));?>

in this case count is correct

[2][4][0][0][31248]=
[2][5][0][0][46619]=

the result of count is 2

but in this case the result is 1

[1][1][0][0][31248]=
[1][1][0][0][46619]=

how i can count dinamically arrays multidimensional? because in anothe case i need to count for example another level of array, like this:

<?$count=array_sum(array_map("count", $array[$key][$key2]));?>

thanks

You could wrap these functions:

$count = count(iterator_to_array(new RecursiveIteratorIterator(
                 new RecursiveArrayIterator($array)
         )));

Replace $array with whichever key you want to apply the count to, like $array[$key][$key2].
