Hi, All,
I can't see the post I sent several hours ago, if repeated, please reply
to this one. Thanks!
System: CentOS 5.5; PHP version is 5.1.6.
I met a strange problem associate with session_save_handler in current
environment(The same code can work well in my local windows platform and
ubuntu system).
I just want to use a customized session save handler to be triggered, so
that I can call my own logic to handling the session. The testing in
local is pretty great but when migration to the VPS, it bring me the
following error:
Fatal error: session_start() [<a
href='function.session-start'>function.session-start</a>]: Failed to
initialize storage module: user (path: /tmp)
The default value for session save handler and session save path in
php.ini are:
session.save_handler = files
session.save_path = "/tmp"
session.name = PHPSESSID
And the bottom are the code for the session handler. I first called
ob_start(), and after calling session::init(), I called session_start().
Then the fatal error happen. It did not trigger any function in the
"session" class.
I tried change the php.ini from session.save_handler = user, but the
error remains. And I found no matter what session.save_handler type is,
after calling session_set_save_handler(), the session.save_handler will
always automatically changed to 'user', that's why the Fatal error info
shows user (path: /tmp).
Can anybody help me out for such error? I was stuck by this issue for
more than 2 days, but still haven't get any clue!
