Modify Sessions Help

[Wstar]

I'm having a problem writing to a session.  Here is my customer session handler:

[code]$SESS_DBHOST = ""; /* database server hostname */
$SESS_DBNAME = ""; /* database name */
$SESS_DBUSER = ""; /* database user */
$SESS_DBPASS = ""; /* database password */

$SESS_DBH = "";
$SESS_LIFE = get_cfg_var("session.gc_maxlifetime");

function sess_open($save_path, $session_name) {
global $SESS_DBHOST, $SESS_DBNAME, $SESS_DBUSER, $SESS_DBPASS, $SESS_DBH;

if (! $SESS_DBH = mysql_pconnect($SESS_DBHOST, $SESS_DBUSER, $SESS_DBPASS)) {
echo "<li>Can't connect to $SESS_DBHOST as $SESS_DBUSER";
echo "<li>MySQL Error: ", mysql_error();
die;
}

if (! mysql_select_db($SESS_DBNAME, $SESS_DBH)) {
echo "<li>Unable to select database $SESS_DBNAME";
die;
}

return true;
}

function sess_close() {
return true;
}

function sess_read($key) {
global $SESS_DBH, $SESS_LIFE;

$qry = "SELECT value FROM sessions WHERE sesskey = '$key' AND expiry > " . time();
$qid = mysql_query($qry, $SESS_DBH);

if (list($value) = mysql_fetch_row($qid)) {
return (string)$value;
}

return (string)"";
}

function sess_write($key, $val) {
global $SESS_DBH, $SESS_LIFE;

$expiry = time() + $SESS_LIFE;
$value = addslashes($val);

$qry = "INSERT INTO sessions VALUES ('$key', $expiry, '$value')";
$qid = mysql_query($qry, $SESS_DBH);

if (! $qid) {
$qry = "UPDATE sessions SET expiry = $expiry, value = '$value' WHERE sesskey = '$key' AND expiry > " . time();
$qid = mysql_query($qry, $SESS_DBH);
}

return $qid;
}

function sess_destroy($key) {
global $SESS_DBH;

$qry = "DELETE FROM sessions WHERE sesskey = '$key'";
$qid = mysql_query($qry, $SESS_DBH);

return $qid;
}

function sess_gc($maxlifetime) {
global $SESS_DBH;

$qry = "DELETE FROM sessions WHERE expiry < " . time();
$qid = mysql_query($qry, $SESS_DBH);

return mysql_affected_rows($SESS_DBH);
}

session_set_save_handler(
"sess_open",
"sess_close",
"sess_read",
"sess_write",
"sess_destroy",
"sess_gc");
session_start();
sess_gc(get_cfg_var("session.gc_maxlifetime"));
?>
[/code]


At the begining of my site I have the following.
[code]
include("includes/session_mysql.php");
require('includes/layout_top.php');
$_SESSION['user']="nli";  //  nli = Not Logged In[/code]

When I check my session user in my database it shows nli for the user.  When i add the line:

[code]$_SESSION['user'] = "Bob";[/code]

so it now looks like this:

[code]
include("includes/session_mysql.php");
require('includes/layout_top.php');
$_SESSION['user']="nli";  //  nli = Not Logged In
$_SESSION['user'] = "Bob";[/code]

When i check the session now when i reload the page.  It still shows nli for the user in the mysql database.  Why does the session not re-write Bob over nli?

I've tried to do the following with no luck:
  a) Delete the session before I tried to rename the user
  b) unset() the session before I tried to rename the user
  c) session_unset() before i tried to rename the user

Why will this not work?  I'm just not getting this. 

One last question.  When I write the following code:

[code]$_SESSION['user']="nli";  //  nli = Not Logged In
session_destroy();
$_SESSION['user'] = "Bob";[/code]

Why do I get this error?

Thanks for any help anyone can give me.

I don't know about the first portion of your post, but in this last part.. don't you mean to use:

sess_destroy(); instead of  session_destroy();

I mean you are using a custom session handler, right?

Yeah, i'm using a custom handler.  Is there a nice custom handler out there i can get?
