Description:
------------
ini_set changes the 'access' parameter of configuration entry to 63 without any reason.

This behaviour did not exist in previous versions and is very easy to reproduce. It is not documented and not in the php 5.6.3 changelog.

Reproduce code:
---------------
<?php
define('CONFIG_ENTRY', 'magic_quotes_runtime');

function dumpini()
{
  $configs = ini_get_all();
  echo 'access value: '.$configs[CONFIG_ENTRY]['access']."\n";
}

dumpini();

echo 'ini_set(\''.CONFIG_ENTRY.'\', 0);'."\n";
ini_set(CONFIG_ENTRY, 0);

dumpini();


Expected result:
----------------
access value: 7
ini_set('magic_quotes_runtime', 0);
access value: 7


Actual result:
--------------
access value: 7
ini_set('magic_quotes_runtime', 0);
access value: 63

Ilia, I think this is the patch that causes the side-effect:

http://cvs.php.net/viewvc.cgi/ZendEngine2/zend_ini.c?r1=1.39.2.2.2.26&r2=1.39.2.2.2.27&pathrev=PHP_5_2

Why it is a problem? As far as I can see, there was a change that now uses some previously unused bits in the access mask, but why it is a bug? Does something that worked before doesn't work now?

I also have the same problem in PHP 5.2.17 version. Does anyone know what means 
"63" in key "access" after call ini_get_all()? Thanks for help in advance.
According to documentation 
(http://www.php.net/manual/en/configuration.changes.modes.php) there sholuld be 
1,6,4 or 7.
