Sorry, I will explain:
<?php
abstract class aSingleton {
private static $_instance;
private final function __construct() {}
public final static function getInstance() {
if (!self::$_instance) {
self::$_instance = new self;
}
return self::$_instance;
}
public final function __clone() {
throw new Exception('denied');
}
}
class cStorage extends aSingleton {
}
$obj = cStorage::getInstance();
?>
Fatal error: Cannot instantiate abstract class aSingleton in
/var/www/html/autosave/cStorage.php on line 8
Why self is of class aSingleton when I call it as
cStorage::getInstance();
Should be of class cStorage

Description:
------------
As I know all functions in PHP are virtual. This mean that $this always
is type of object, but self is type of class where function is called.
So when I try to execute new self, it's creating instance of class
where function was executed. Maybe self should be something like
virtual too?
