Bug #40998 The length of key of session limited
Submitted: 2007-04-04 19:02 UTC Modified: 2007-04-04 19:52 UTC
From: jason dot polaris at gmail dot com Assigned:
Status: Closed Package: Session related
PHP Version: 4.4.5 OS: Windows XP
Private report: No CVE-ID:

Currently I am trying to store a lot of data in the session (i.e. filename and things related to that particular file)
However some filename(with full path) can be more than 300 characters, and it is not stored if I use the path as a $_SESSION key.
Any key that contains less than 250 characters surely works well.

Reproduce code:
  $_SESSION['asdklfjsldfkjsldkfj(more than 300 chars)']['ABC'] = 1;


Expected result:
When reloading (or redirect to another page that reads session)
$_SESSION['asdklfjsldfkjsldkfj(more than 300 chars)']['ABC'] will equals to 1

Actual result:
The session array ($_SESSION['asdklfjsldfkjsldkfj(more than 300 chars)']['ABC']) is simply not set

What kind of session storage are you using?

Currently I am using my XP machine, so I just put it in:

When I look inside the sessiondata folder, there is serveral files. I use my text editor to search for my target "key", I found:
which is part of a key that I had set. However, there is even more character goes beyond Windows_CH.............
For others, e.g.

The actual statement I have used:
$_SESSION['L_CHR058_CHR047AutoPlayv2_CHR047Autoplay_CHR032in_CHR032Windows_CHR032XP_CHR032_CHR032Automatically_CHR032Detect_CHR032and_CHR032React_CHR032to_CHR032New_CHR032Devices_CHR032on_CHR032a_CHR032System_CHR032_CHR045_CHR045_CHR032MSDN_CHR032Magazine_CHR044_CHR032November_CHR0322001_files_CHR047t_CHR046gif']['P3R'] = 1;
(I know, a little bit long...)
