To do this I have my classes register themselves in a global array.
For example a mysql class which gets used a lot does this in its constructor:
function mysql_class($db='',$ini=''){
global $class_ref;
$class_ref["mysql_class"] =& $this;
.
.
.
}
Then any class that needs access to mysql_class does this in the constructor:
class galleryClass(
var $mysql;
var $db = 'test';
function galleryClass(){
global $class_ref;
if(!empty($class_ref['mysql_class'])):
$this->mysql =& $class_ref['mysql_class'];
else:
$this->mysql = new mysql_class();
endif;
if(!empty($this->mysql)):
$this->con = $this->mysql->get_handle($this->db);
endif;
.
.
}
.
.
}
This way there is only need for 1 instance of the mysql class.
I use global as a bad habit, but you can do the same with $GLOBALS['class_ref']
