Bug description:Presence of __invoke makes protected __construct visible as
callable
Description:
------------
Presence of __invoke causes is_callable($obj, '__construct') returns true,
instead of false when it's called out of class scope.
Also, is_callable('class', '__construct') yields true even if __construct
is set
to protected (which is clearly not connected with __invoke issue, but I
suppose
that is caused by the same underlying problem).
Although setting __construct private/protected seems a little bit pervert,
if it
is not interdicted by language semantics, visibility testing should give
good
results.
Test script:
---------------
class Singleton {
protected static $aInstances = array();
final protected function __construct(){}
public static function getInstance(){
$sClassName = get_called_class();
if (!isset(static::$aInstances[$sClassName])) {
static::$aInstances[$sClassName] = new
$sClassName();
} // if
return static::$aInstances[$sClassName];
} // getInstance
} // class
class SingletonWithInvoke extends Singleton {
final protected function __invoke(){}
} // class
var_dump(is_callable(Singleton::getInstance(), '__construct'));
var_dump(is_callable(SingletonWithInvoke::getInstance(),
'__construct'));
var_dump(is_callable('Singleton', '__construct'));
var_dump(is_callable('SingletonWithInvoke', '__construct'));
Expected result:
----------------
bool(false) bool(false) bool(false) bool(false)
Actual result:
--------------
bool(false) bool(true) bool(true) bool(true)
