Question

I have the function:

function get_current_users($current_users) 
{
global $db;
$current_users = $db->EscapeString($current_users);
$total_current_users = $db->QueryFetchArray("SELECT COUNT(*) FROM users AS total_current_users");
return $total_current_users['total_current_users'];

}

But I have no clue how to output the result, I’ve tried the following options but nothing displays:

 `<?$total_current_users?>
 <?['$total_current_users']?>
 <?=data['$total_current_users']?>`

Answer 1

If you are certain that your function does what it’s supposed to, I guess the two equivalent methods would gain you the output:

<?= get_current_users() ?> or
<?php echo get_current_users() ?>

As a note: I don’t see the point of your argument $current_users that you escape — because it never gets use in the subsequent query.
