How did you verify that the write handler is not called? Note that during the request
shutdown the write/close handlers cannot send any data to the browser.

I'm trying to setup a user session module using a postgre (6.2.3) database. the
script that I'm supplying defines the functions for storing session data. If I force
the session data into the database the read function works and I can retrieve the
session data. However, the write function never gets called so data is never stored
in the database. This is simular to problems reported in #8772 and #9002. There is a
difference though. Those reports indicate that register_globals was off. In my case
register_globals was on. Here is the script I'm using to test the session module.
============================================
<?php
$sess_pg = array();
$sess_pg["open_connection"] = true; // Establish a Pg connection on session
startup?
$sess_pg["hostname"] = "localhost"; // Pg hostname
$sess_pg["port"] = "5432"; // Pg port
$sess_pg["db"] = "php_sessions"; // Database where to store the sessions
$sess_pg["table"] = "sessions"; // Table where to store the sessions
function sess_pg_open($save_path, $sess_name)
{
global $sess_pg;
// Establish a Pg connection, if $sess_pg["open_connection"] is true
if ($sess_pg["open_connection"])
{
$sess_pg["connection"] = pg_pconnect( $sess_pg["hostname"],
$sess_pg["port"],
$sess_pg["db"]) or
die(pg_errormessage($sess_pg["connection"]));
}
return(true);
}
function sess_pg_read($sess_id)
{
global $sess_pg;
echo "HELP ME<br>";
$query = "SELECT data ";
$query .= "FROM ".$sess_pg["table"]." ";
$query .= "WHERE id = '$sess_id'";
echo "$query<BR>";
// Select the data belonging to session $sess_id from the Pg session table
$result = pg_exec($sess_pg["connection"], $query) or
die(pg_errormessage($sess_pg["connection"])) or
die(pg_errormessage($sess_pg["connection"]));
#
// Return an empty string if no data was found for this session
//if(pg_numrows($result) == 0)
if(!($sess_pg["present"] = pg_numrows($result)))
{
echo "Nothing<BR>";
return("");
}
echo "Records: ".$sess_pg["present"]."<BR>";
// Session data was found, so fetch and return it
$row_number = 0;
$row = pg_fetch_array($result,$row_number);
pg_freeresult($result);
echo "DATA: ".$row["data"]."<BR>";
return($row["data"]);
}
function sess_pg_write($sess_id, $val)
{
global $sess_pg;
if(!$sess_pg["present"]){
// Write the serialized session data ($val) to the Pg ession table
$query = "INSERT INTO ". $sess_pg["table"] ." (id, data, t_stamp) ";
$query .= "VALUES ($sess_id, $val, now())";
$result = pg_exec($sess_pg["connection"], $query) or
die(pg_errormessage($sess_pg["connection"]));
}else{
// Write the serialized session data ($val) to the Pg ession table
$query ="UPDATE ".$sess_pg["table"];
$query .=" SET data = '$val', t_stamp = now() ";
$query .=" where id = '$sess_id'";
$result = pg_exec($sess_pg["connection"], $query) or
die(pg_errormessage($sess_pg["connection"]));
}
return(true);
}
function sess_pg_destroy($sess_id)
{
global $sess_pg;
// Delete from the Pg table all data for the session $sess_id
$query ="DELETE FROM ".$sess_pg["table"]." ";
$query .="WHERE id = '$sess_id' ";
$result = pg_db_query($sess_pg["connection"], $query) or
die(pg_errormessage($sess_pg["connection"]));
return(true);
}
function sess_pg_gc($max_lifetime)
{
global $sess_pg;
// Old values are values with a Unix less than now - $max_lifetime
$old = time() - $max_lifetime;
// Delete old values from the Pg session table
$result = pg_db_query($sess_pg["connection"], "DELETE FROM ".$sess_pg["table"]."
WHERE UNIX_TIMESTAMP(t_stamp) < $old") or
die(pg_errormessage($sess_pg["connection"]));
return(true);
}

session_set_save_handler("sess_pg_open", "", "sess_pg_read", "sess_pg_write",
"sess_pg_destroy", "sess_pg_gc");
session_start();
session_register("foo");

$foo++;
