Bug description: private var accessible from static class
Description:
------------
Private property of initialized class, is accessible from static version
of the same class.
Reproduce code:
---------------
class FOO {
private $bar = 0;
private static $instance = false;
public static function get_instance(){
if(self::$instance === false) self::$instance = new FOO;
return self::$instance;
}
public static function set_bar( $b ){
$foo = FOO::get_instance();
$foo->bar = $b;
}
public static function dump_bar(){
$foo = FOO::get_instance();
echo $foo->bar;
}
}
FOO::set_bar( 1 );
FOO::dump_bar();
$foo = FOO::get_instance();
echo $foo->bar;
Expected result:
----------------
Fatal error: Cannot access private property FOO::$bar in
/var/www/index.php on line 10
I should not be able to write to a private property from "outside". (Even
thou it's the same code for both classes (static and initialized).)
Actual result:
--------------
1
Fatal error: Cannot access private property FOO::$bar in
/var/www/index.php on line 20
Well, I can write to the private property and I can read it, from inside
the static.
The error is when I try to access it from completely "outside". And that
error is correct.
Same result for private and protected.
