ID: 39619 Updated by: vrana@php.net Reported By: thbley at gmail dot com -Status: Open +Status: Closed Bug Type: Documentation problem Operating System: WinXP SP2 PHP Version: 5.2.0 New Comment: This bug has been fixed in the documentation's XML sources. Since the online and downloadable versions of the documentation need some time to get updated, we would like to ask you to be a bit patient. Thank you for the report, and for helping us make our documentation better. "Current working directory is changed with some SAPIs if session is closed in the script termination. It is possible to close the session earlier with session_write_close()."

I think this would save the people a lot of time if they know that they have to use absolute paths here. ------------------------------------------------------------------------ [2006-11-24 15:20:01] tony2001@php.net The fact that ext/session is affected by shutdown order sequence is a known problem, but unfortunately noone is willing to rewrite ext/session from scratch, which is most likely required to get this problem fixed. ------------------------------------------------------------------------ [2006-11-24 15:13:04] thbley at gmail dot com Yes adding session_write_close() works but this means I need to call it every time I call exit(), die(), return etc. ... not very comfortable for bigger programs. The documentation doesn't state the directory change, see http://de.php.net/manual/en/function.session-set-save-handler.php ------------------------------------------------------------------------ [2006-11-24 15:04:41] tony2001@php.net Please add session_write_close() to the end of the script and see if it works for you. ------------------------------------------------------------------------ [2006-11-24 14:59:18] thbley at gmail dot com Description: ------------ I'm using a custom session save handler. When the write function is called, the current directory is changed to the apache bin directory. This breaks when using relative paths for storing session data. Reproduce code: --------------- session_set_save_handler("none","none","read","write","none","none"); session_start(); echo "2 ".getcwd()."<br>"; function none() { return true; } function read($id) { echo "1 ".getcwd()."<br>"; } function write($id,$val) { echo "3 ".getcwd()."<br>"; } Expected result: ---------------- 1 H:\sgs\src Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at H:\sgs\src\test_session.php:14) in H:\sgs\src\test_session.php on line 5 2 H:\sgs\src 3 H:\sgs\src Actual result: -------------- 1 H:\sgs\src Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at H:\sgs\src\test_session.php:14) in H:\sgs\src\test_session.php on line 5 2 H:\sgs\src 3 H:\Development\Apache2_php5\bin ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=39619&edit=1
