Currently I am running Apache 2.0.45 with PHP 4.3.2RC2, and not any of my scripts store sessions. When i use the script:
<?php
//ini_set("session.save_path","e:\\program files\\webserver\\php\\tmp");
$foo = "bar";
session_start();
session_register("foo");
session_write_close();
?>
i get the following error messages:
Warning: session_start(): open(/tmp\sess_c61f98f39e73fa535a14be0dde19a36e, O_RDWR) failed: No such file or directory (2) in E:\program files\Webserver\www-docs\session.php on line 4

Warning: session_write_close(): Your script possibly relies on a session side-effect which existed until PHP 4.2.3. Please be advised that the session extension does not consider global variables as a source of data, unless register_globals is enabled. You can disable this functionality and this warning by setting session.bug_compat_42 or session.bug_compat_warn to off, respectively. in E:\program files\Webserver\www-docs\session.php on line 6

Warning: session_write_close(): open(/tmp\sess_c61f98f39e73fa535a14be0dde19a36e, O_RDWR) failed: No such file or directory (2) in E:\program files\Webserver\www-docs\session.php on line 6

Warning: session_write_close(): Failed to write session data (files). Please verify that the current setting of session.save_path is correct (/tmp) in E:\program files\Webserver\www-docs\session.php on line 6.
When i remove the slashes, the errors stop(except for the 2nd, but that's because i didn't set session.bug_compat_warn to off). The most strange error for me is 'Warning: session_write_close(): Failed to write session data (files). Please verify that the current setting of session.save_path is correct (/tmp) in E:\program files\Webserver\www-docs\session.php on line 6', because in my php.ini, session.save_path isn't set to /tmp, but to e:\\program files\\webserver\\php\\tmp. Also, PHP doesn't take over the settings for session.name or any other session related option. I am sure thou that I am editing the right php.ini, because phpinfo() tells me the exact path to my php.ini, that I was editing. I always reset the server after I made changes to my php.ini, so that isn't the problem either, and I know that the path is valid, because sessions work when I use the command ini_set("session.save_path","the path"), sessions DO get stored.
One more note: when I read my phpinfo, it also gives the 'standard settings' for sessions, even thou I have edited the php.ini. All the other settings are taken over perfectly by PHP.

How can I solve this problem, without having to add ini_set to every file(or including a file which does this for me)? In other word, can this be fixed, and if yes, how?
