PHP Bug Type: Class/Object related
Bug description: Parentheses around returned object cause a parse error
Description:
------------
I use Singleton classes in my code. In each of them there must be a
function that returns the instance of the object of that class (or creates
that object before). The problem occurs, when I try to put that method
insinde parentheses, like (MobilDB::GI())->test(); in the following
example. Please notice, that MobilDB::GI()->test(); works perfectly, so
the problem seems to be related to the parentheses around MobilDB::GI().
Reproduce code:
---------------
class MobilDB {
private static $instance = null;
private function __construct() {
echo "const";
}
public static function GI() {
if (self::$instance == null) {
self::$instance = new MobilDB;
}
return self::$instance;
}
function test() {
echo "test";
}
}
(MobilDB::GI())->test();
Expected result:
----------------
I expected the constructor from the MobilDB class to be run (as this is
the first instance of GI() function and appropriate object must be
created) and then the test() method from the same class to be run.
The expected output was "consttest".
Actual result:
--------------
Parse error: parse error, unexpected T_OBJECT_OPERATOR in
D:\www\mobil\m.php on line 8
