function without global

[sissy]

Hi there folks,

Is it possible to code a function without the use of the global var?

<?

// basic mysql class
$db = new db();
$db->connect();

function users() {

//global $db;  << can it be done without this global var.

$query = $db->query("SELECT COUNT(id) FROM login");
while ($users = $db->fetch_row($query)) {
    echo $users[0];	 
}
}

?>

I have given it a fair go without any luck or creating a monster.

Any help appreciated, thanks folks.

function users(&$db) {
    $query = $db->query("SELECT COUNT(id) FROM login");
    while ($users = $db->fetch_row($query)) {
        echo $users[0];     

    }
}

users($db);

Hi PHPThorsten,

thanks very much works like a treat.

could you maybe give me a quick summary on whats happening and what does the "&db" do or better still whats it called so i can look it up in the manual dont think i have ever came across that.

Thanks again for the fast response.
