If you want to show total number of registered users on your WordPress site? add this code to your theme’s functions.php file.
// Function to return user count
function wpe_user_count() {
$usercount = count_users();
$result = $usercount['total_users'];
return $result;
}
// Creating a shortcode to display user count
add_shortcode('total_user_count', 'wpe_user_count');
That code creates a shortcode that allows you to display total number of registered users on your site. Now you just need to add this shortcode to [total_user_count] your post or page where you want to show the total number of users.
