Operating System: *
PHP Version: 5.2.10
New Comment:
I'm having the same issue. My problem is that I upgraded from PHP
5.2.9 to 5.2.11 and set up APC at the same time. The problem actually
affected my custom session handler. After finding this ticket I
disabled APC and restarted apache, but the problem persists.
My code to recreate:
session.class.php
------------------
<?php
/**
* These are our session handler functions
*/
class Session {
/**
* Open a session
*
* @return bool true
*/
public static function ses_open() {
return true;
}
/**
* Closes the session, after cleaning up.
*
* @return bool true
*/
public static function ses_close() {
self::ses_clean(ini_get('session.gc_maxlifetime'));
return true;
}
/**
* Reads the data from the session.
*
* @param string $session_id
* @return unknown
*/
public static function ses_read($session_id) {
$db = db::get_instance();
$q = "SELECT `data` FROM `sessions` WHERE
`id`=".quote_smart($session_id);
if (($r = $db->query($q)) && $r->num_rows > 0) {
$i = $r->fetch_object();
return $i->data;
}
return false;
}
/**
* Writes the session
*
* @param string $session_id
* @param string $data - serialized version of $_SESSION
* @return unknown
*/
public static function ses_write($session_id, $data) {
/**
* I guess that our database connection is closed before this
runs,
but the
* static variable is not reset. We run the destroy instance
first,
so that
* the singleton knows to create a new instance
*/
db::destroy_instance();
$db = db::get_instance();
$uid = (isset($_SESSION['uid']))? $_SESSION['uid']:'';
$q = "REPLACE INTO `sessions` (`id`, `uid`, `ip`, `data`) VALUES
(".quote_smart($session_id, $uid, $_SERVER['REMOTE_ADDR'], $data).')';
return $db->query($q);
}
/**
* Destroys the session, and clears our 'remember me' cookie, so we
can use this
* to log a user out
*
*
* @param string $session_id
* @return bool
*/
public static function ses_destroy($session_id) {
$db = db::get_instance();
$q = "DELETE FROM `sessions` WHERE
`id`=".quote_smart($session_id);
if(isset($_COOKIE['user'])){
setcookie("ezd_user", '', time()-(60*60*24*7), '/', '');
//60*60*24*7=secs*mins*hrs*days=7days
}
return $db->query($q);
}
/**
* Cleans up (removes) old sessions
*
* @param int $max - How old "old" data is (in seconds)
* @return bool
*/
public static function ses_clean($max) {
$db = db::get_instance();
$q = "DELETE FROM `sessions` WHERE `access` < NOW() - INTERVAL
{$max}
SECOND";
return $db->query($q);
}
}
test.php
-----------
/**
* Starts a session. Since we need to do this in more than one place,
this
* function sets the session name and handler, then starts it.
*/
function start_session() {
require_once('session.class.php');
session_name('EZD_ID');
/*
session_set_save_handler( array('Session','ses_open'),
array('Session','ses_close'),
array('Session','ses_read'),
array('Session','ses_write'),
array('Session','ses_destroy'),
array('Session','ses_clean'));
*/
session_start();
}
start_session();

Same problem here (Gentoo Linux PHP 5.2.10).
This bug seems some way related to this
http://bugs.php.net/bug.php?id=48787

I can reproduce the bug with or without APC installed/enabled.

Same grave bug here! But here it happens only when APC (3.0.19) is
enabled. Can the OP confirm it happens only with APC as well?

Description:
------------
There is a bug with cyclic inclusion of files with class definition.
There are three classes - A, B, C - each placed in a separate file -
A.php, B.php, C.php - all in the same directory.
B is a derived class of A, C is a derived of B.
So, B.php includes A.php (using require_once), C.php includes B.php.
A.php contains both class A and function f(), which is subsequently
called. f() includes 'C.php'.
When trying to request B.php (or include it from another file) I get
Fatal error: Class 'B' not found C.php on line 4.
Reproduce code:
---------------
Three files here:
--------[ A.php ]--------
<?
class A {}
function f()
{
include 'C.php';
}
f();
?>
--------[ B.php ]--------
<?
require_once 'A.php';
class B extends A {}
?>
--------[ C.php ]--------
<?
require_once 'B.php';
class C extends B {}
?>
Expected result:
----------------
No error when requesting or including B.php.
Actual result:
--------------
Fatal error: Class 'B' not found in /srv/www/test/C.php on line 4
