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

Please add session_write_close() to the end of the script and see if it works for you.

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

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.

So can you update the documentation on http://www.php.net/manual/en/function.session-set-save-handler.php ? I think this would save the people a lot of time if they know that they have to use absolute paths here.

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()."
