A singleton, e.g. (assuming PHP5)

class TMyClass {
private static $instance = NULL;

public static function getInstance() {
if (!isset(self::$instance)) {
self::$instance = new self();
}
return self::$instance;
}

...
}

Then wherever you need that instance, you just have to get it:

$foo = TMyClass::getInstance();
