Bug description: each() erratic behaviour with objects
Description:
------------
Using each() to iterate through an object will produce weird results in
two respects:
1. It will expose private and protected members alongside public ones.
2. For private and protected members, the keys (names) are jumbled.
Yes, I know that this behaviour is known and that the manual page for
each() warns about this. But such an inconsistency should not exist.
Desirable consistent behaviour:
a) Produce the same results as foreach() (show only public members).
or
b) Refuse to work with objects altogether and state so in the manual.
Reproduce code:
---------------
<?php
class Example {
private $priv = 1;
protected $prot = 2;
public $pub = 3;
}
$obj = new Example();
while (list($key, $val) = each($obj)) {
printf("%s = %s\n", $key, $val);
}
?>
Expected result:
----------------
pub = 3
Actual result:
--------------
[NUL]Example[NUL]priv = 1
[NUL]*[NUL]prot = 2
pub = 3
where [NUL] is the null (0x00) character
