PHP determines the dimensions of an array Array (encapsulated function)_PHP tutorial

PHP determines the dimensions of an array Array (encapsulated function)

Sometimes I need to determine the dimensions of an array. I checked a lot of things on the Internet with similar writing methods, but I couldn’t figure out what they meant. Here’s what I wrote:

<code class="hljs" php="">    private static function array_depth($array) {
        if(!is_array($array)) return 0;
        $max_depth = 1;
        foreach ($array as $value) {
            if (is_array($value)) {
                $depth = array_depth($value) + 1;

                if ($depth > $max_depth) {
                    $max_depth = $depth;
                }
            }
        }
        return $max_depth;
    }</code>
