尝试计数多个数组时,无法计数超过第一个数组的值

以下内容发生在WordPress中。。

// get the current page author

$curauth    = (isset($_GET['author_name'])) ? get_user_by('slug', 
$author_name) : get_userdata(intval($author));

// get the current page authors id (in this case its 2)

$author_id  = $curauth->ID;

// set the $args to get the value of the users meta_key named 'followers'

$args = array(
    'meta_key'     => 'followers',
);

// setup the get_users() query to use the $args

$users  = get_users($args);

// setup a foreach loop to loop through all the users we just queried getting the value of each users 'followers' field

foreach ($users as $user) {

// $user->folllowers returns:
// 2
// 1,3,5
// 3,4,5
// 3,5,1,4
// 3,4,5,1
// 1,2
// which is a series of comma separated strings.
// so then i turn each string into an array:

    $array = array($user->followers);

    // go through each array and count the items that contain the authors id

    for($i = 0; $i < count($array); $i++) {
        $counts = array_count_values($array);
        echo $counts[$author_id];
    }

}

你能帮我找出我做错了什么吗?
