Description:
------------
If the object to invoke is stored in a static property or is returned
by a static function __invoke will not be called.
Especially for singletons is this extremly missleading.
Either it is an documentation problem or something other is wrong.
Actual documentation:
The __invoke method is called when a script tries to call an object as
a function.
Reproduce code:
---------------
class foo
{
public static $instance = null; //only public for this example
public static function get()
{
if(is_null(self::$instance))
self::$instance = new self;
return self::$instance;
}
public function __invoke($name)
{
echo 'Hello '.$name;
}
}
//1)
foo::get()('World');
//2)
foo::get();
foo::$instance('World');
//3)
$bar = foo::get();
$bar('World');
Expected result:
----------------
1) //Here is the parsing-error partial expected
Hello World
2)
Hello World
3)
Hello World
Actual result:
--------------
1)
Parse error: parse error in test.php on line 23
2)
Notice: Undefined variable: instance in test.php on line 27
Fatal error: Function name must be a string in test.php on line 27
3)
Hello World //Behavior as expected
