[PHP-DEV] PHP 4.0 Bug #7477 Updated: Session Write Failure From: sasha <email protected>
Date: 10/28/00

ID: 7477
Updated by: sasha
Reported By: tim.parkin <email protected>
Status: Closed
Bug Type: *Session related
Assigned To: alex <email protected>
Comments:

The text below should be added to the documentation of the session extension:

"The session_module() with a parameter destroys the current session and overwrites the values of the user handlers if such are set with the session_set_save_handler() function. Basically, session_module with a parameter should be invoked in the beginning of the script, before any of the session_set_handlers() or session_start() functions."

Ater posting this I removed the session_module command and it started working... I am going to try replicating this behaviour on my home system and report here on my findings..

I am having major problems getting a custom session handler (oci8 based) to work in php-4.0.2 and php-4.0.3. I have set session.save_handler=user in the php.ini file and it registers in phpinfo(). I have also set the module_name specifically using :

session_module_name('user');

The problem is that the write function does not work. I have seen many posts showing the same problem (admittedly some of them are a result of not setting save_handler) and as yet have found no 'official' response.

This seems to have been around since 4.0.1pl2.

I have tried printing from the write function and also writing to a file whilst presuming that the session write is not called till after the page has finished processing.

This is a major blow to a project we are working on. We can find ways around this but it has knocked our confidence in PHP somewhat.

A prompt reply would be greatly appreciated.

oci_session_handler is avaialable on request although the normal test handler fails to write also ie..

<?php
function open ($save_path, $session_name) {
echo "open ($save_path, $session_name)n";
return true;
}
function close () {
echo "closen";
return true;
}
function read ($key) {
echo "read ($key)n";
return "foo|i:1;";
}
function write ($key, $val) {
echo "write ($key, $val)n";
// Test to see if output to page is failing due to write being executed after user output is finished
$fp = fopen("temp",w);
fwrite($fp,"write ($key, $val)",4096);
fclose($fp);
return true;
}
function destroy ($key) {
return true;
}
function gc ($maxlifetime) {
return true;
}

session_set_save_handler ("open", "close", "read", "write", "destroy", "gc");
?>

Thanks
