Pass an object as a variable??

[Anon]

In short is this legal??
<pre>

include classes pages and instantiate

require($DOCUMENT_ROOT . "/inc/classes.php");

$Mydb = new db($DBHOST, $DBUSER, $DBNAME, $DBPWD);
$MyUser = new User($PHPSESSID, $Mydb);
</pre>

classes.php has this...
<pre>
class User
{

function User($PHPSESSID, $Mydb)
{
$temp_result = $Mydb->Query("select sessionID from session where sessionID = '$PHPSESSID'") or die ("query failed");
if (mysql_num_rows($temp_result))
{
//session_register();
echo "phpsessid found; user here already";
}

}</pre>

Yes it's completely legal. You object should be passed as a referance (I believe that PHP automatically does this for objects so you don't have to) to the class/function/method which then uses it.
