Object Scope

[Chuck Brockman <cjbrockman@xxxxxxxxx>]

What is the best practice for calling objects that are to be used
throughout a users site visit.  For example, I have a members class
with two classes that extend this class.  Is it best to instantiate
the object in the $_Session scope or make individual calls to the
class/object.

For example:

class members {
	var $iMemberID;
	var $iProfileID;
	var $dbServer;
	var $dbUser;
	var $dbPassword;
	var $dbDSN;
	var $_dbServer;
	var $_dbUser;
	var $_dbPassword;
	var $_dbDSN;
	
	function members($dbServer, $dbUser, $dbPassword, $dbDSN){
		$this->_dbServer = $dbServer;
		$this->_dbUser = $dbUser;
		$this->_dbPassword = $dbPassword;
		$this->_dbDSN = $dbDSN;
	}
}

I have created a _global.php file that instantiates the object such as:

if(!isset($_SESSION["objMember"])){
     $_SESSION["objMember"] = new members($aSiteSettings["sDBServer"],
$aSiteSettings["sDBLogin"], $aSiteSettings["sDBPassword"],
$aSiteSettings["sDSN"]);
}

Or am I way off base altogether (wouldn't be too suprises)?

Thanks!
