#48565 [NEW]: Transparent session ID occasionally not added
From: bill at rubgrp dot com
Operating system: Linux (Fedora 11)
PHP version: 5.2.9
PHP Bug Type: Session related
Bug description: Transparent session ID occasionally not added
Description:
------------
Sometimes when adding a session ID to a URL, it is not added after
existing parameters, but rather iafter the closing quote for the URL. For
example, an anchor tag of '<a href="xyzzy.php?arg=y">' would be rewritten
as '<a href="xyzzy.php?arg=y"?PHPSESSID=123...>' instead of '<a
href="xyzzy.php?arg=y&PHPSESSID=123...">'.
This appears to be similar to the issue reported in bug #3411. It appears
to be buffer related, since adding or subtracting a few characters from
earlier in the page can introduce or eliminate the error. As mentioned in
#3411, turning on output buffering eliminates the problem.
This seemed to work correctly through 5.2.5, but has not worked since
5.2.6.
Reproduce code:
---------------
Since it appears to be dependent on the number of bytes in the buffer, it
can't be reproduced in 20 lines. Here is a link to a page that generated
the examples:

Expected result:
----------------
<a
href="custmain.php?srch=000006&PHPSESSID=ho7ev8p2bmc16rotaih4duat82">000006</a>
...snip...
<a
href="custmain.php?srch=000007&PHPSESSID=ho7ev8p2bmc16rotaih4duat82>000007</a>
..snip...
<a
href="custmain.php?srch=000008&PHPSESSID=ho7ev8p2bmc16rotaih4duat82">000008</a></td>
Actual result:
--------------
<a
href="custmain.php?srch=000006&PHPSESSID=ho7ev8p2bmc16rotaih4duat82">000006</a>
...snip...
<a
href="custmain.php?srch=000007"?PHPSESSID=ho7ev8p2bmc16rotaih4duat82>000007</a>
..snip...
<a
href="custmain.php?srch=000008&PHPSESSID=ho7ev8p2bmc16rotaih4duat82">000008</a></td>
(The first and third are correct; in the second line the session ID is
added after the closing quote on the href value.)
