Description:
------------
If you have a property name containing a NULL character, some PHP routines like print_r() will truncate the name, most likely due to C-string processing limitations.

I know PHP syntax doesn't permit NULL characters within attribute names, however, it's easily done when the name is contained in a variable. The only limitation seems to be that an attribute cannot start with NULL. Since it's "allowed," then PHP should fully support its effects.

Reproduce code:
---------------
<?php
$c = new stdClass;
$a = "HIDDEN\000-TEXT";
$c->$a = 'foo';
print_r($c);
?>

Expected result:
----------------
stdClass Object ( ["HIDDEN\000-TEXT"] => foo )

Actual result:
--------------
stdClass Object ( [HIDDEN] => foo )
