shimu666 on "User counter on my site"

Hello guys, i'm a beginner in wordpress.

I want to insert a counter of registered user
i found this php code :

<?php $wpcode_user_count = $wpdb->get_var("SELECT COUNT(*) FROM $wpdb->users;");?>
We Are <?php echo '' . $wpcode_user_count ; ?> Users

but i want to insert digit before number
When i display it i got only for exemple :
we are 12 users but i would like to display it : we are 0012 user
for limited registration
