I do it this way
$class_ref = array()
class db{
function db(){
global $class_ref;
$class_ref['db'] =& $this;
}
}
class a {
var $db;
function a{
global $class_ref;
if(isset($class_ref['db'])){
$this->db =& $class_ref['db'];
}else{
$this->db = new db();
}
}
}
using $class_ref you can register all classes thay may be shared.
