Passing objects using the magic __sleep() and __wakeup() methods through sessions fail.

In the best case the script fails without error. In the worst, an integer in session turns into the value of the PHP session ID and the object is not registered.

Yasuo Ohgaki guesses it's a serialize/unserialize problem.

Make log :

/usr/src/web/php/php4/ext/standard/var_unserializer.re: In function `php_var_unserialize':
/usr/src/web/php/php4/ext/standard/var_unserializer.re:304: warning: comparison is always false due to limited range of data type

Forgot to tell : asking for .phps will show you the source in the /test/session/ directory.

This will be next my target to fix :)

Version update

I just take a look at what is going on, __sleep and __wakeup is messed badly. It does not work at all and even crashes...

Could you try CVS version to see if this bug is fixed?
 [2002-04-03 11:06 UTC] yohgaki@php.net 
I just tested. It does not work.

I have the same problem running apache 2.0.35 and php 4.2 RC3 under Win2K ...

I use php 4.2.1 as apache module on a win95 system and it crashes whenever I try to serialize an object (in a session or otherwise) that has a __sleep() function.

Bug remains (Apache crash)
SERVER_SOFTWARE: Apache/1.3.26 (Win32) PHP/4.2.3 
OS: Win2000
Apache: 1.3.26

Sample Code:
<?php
class A {
  function A() {}
  function __sleep() {return;}
}
$a = new A();
$stream = serialize($a);
?>

Please try using this CVS snapshot:

  http://snaps.php.net/php4-latest.tar.gz
 
For Windows:
 
  http://snaps.php.net/win32/php4-win32-latest.zip

Cannot replicate this using latest CVS on Windows or Linux.
