## #54497 — Sebastian Bergmann — 2011-08-10T20:12:41+00:00

Is this exepcted behaviour?

    ➜  ~  cat test.php
    <?php
    class Foo {
        public static function bar() {
            print __METHOD__ . "\n";
        }
    }

    $foo = new Foo;
    $foo::bar();


    ➜  ~  php test.php
    Foo::bar

  I, for one, was surprised that this does what it does with PHP 5.3 and
  PHP 5.4 (do not have older version of PHP hand).

This is how FETCH_CLASS works now - when it has an object in where it 
expects class name, it uses object's class. We could call toString() 
instead but that might be even more surprising.

Well, FETCH_CLASS has always worked like that, but previously (<5.3)
variables for class references were only allowed as part of the "new"
statement,
e.g. new $obj; The semantic remains the same, only that now variables
are also allowed for :: calls (since 5.3).
