PHP Multidimensional Nested Array count

Today We were working on Simple PHP code that had best way to understand arrays structured like this:

$item_no = [
    'a' => [ 1, 2, 3, 4 ],
    'b' => [ 5, 6, 7 ],
];

We needed to simple calculate the total number of items in the nested php arrays. I didn’t ANY find a PHP function to help me with that therefor We came up with this idea:

$total_count = array_sum( array_map( 'count', $item_no ) ); // This returns 7.

How this works

The array_map( ‘count’, $item_no ) part replaces the subarrays in $item_no with the result of calling count()on them:

$subarray_counts = array_map( 'count', $item_no );
var_dump( $subarray_counts );

/*
 * Output:
 *
 * array(2) {
 * 'a' =>
 * int(4)
 * 'b' =>
 * int(3)
 * }
 */

The array_sum() PHP function then calculates the Addition of these item counts.
