Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to
report
a bug at http://bugs.php.net/how-to-report.php

using each() on objects is a legacy feature, the NULL-bytes are part of the internal representation
of private and protected elements.

Description:
------------
When using the each() function on objects, private and protected variables gets a NUL character
around them (see expected result).

Create the test script and view it in a browser (I used Firefox 11.0). 

If you send an email with the output, the mail() function will just truncate the message after the
NUL character

Test script:
---------------
class Foo
{
   public $a;
   protected $b;
   private $c;

   function bar($value) {
      echo $value;
   }
}

$tmp = new Foo();

while(list($key, $value) = each($tmp)) {
   var_dump($key);
}

Expected result:
----------------
string(1) "a"
string(4) "*b"
string(6) "Fooc"

Without the NUL character

Actual result:
--------------
string(1) "a"
string(4) "�*�b"
string(6) "�Foo�c"

� = NUL character, ASCII code (dec): 0
