foreach on an object is allowed. You aren't seeing anything because the $obj is empty.

Description:
------------
Hello

If passing a variable (let's say a stdClass) to the foreach method, it does not produce an
error. It silently does not loop the object (since it cannot).

I'm no expert, but I'd say that at least a warning should be raised if trying to iterate a
non-array object. I'm sorry if this is intentional, but I do believe an error was raised in
5.6.


Test script:
---------------
$obj = new stdClass();

foreach ($obj as $anObj) {
    error_log("nothing is output here, obviously, but no error either");
}

Expected result:
----------------
I expect an error or warning to occur, since I'm traversing a non-array.

Actual result:
--------------
Nothing happens at all.
