protected static $instance = null;
final public static function getInstance()
{
if(null !== static::$instance){

Description:
------------
The test script output:
Notice: Undefined variable: this
Instead $this is referenced as $instance
Attempting to do $this = $instance; returns:
Fatal error: Cannot re-assign $this
Test script:
---------------
abstract class singleton
{
final public static function getInstance()
{
if(null !== static::$instance){
return static::$instance;
}
static::$instance = new static();
return static::$instance;
}
}
class myclass extends singleton
{
protected $var='foo';
public function bar()
{
echo $this->var;
}
}
$myclass = myclass::getInstance();
$myclass->bar();
Expected result:
----------------
I expected $this to hold the same value as $instance
Actual result:
--------------
Notice: Undefined variable: this
------------------------------------------------------------------------
