[PHP] Failed to initialize session module

[news.php.net]

Hi guys, having trouble with my win2k install of php 4.3.0 - can't run
sessions! I have some test code:

?php
/*
  SM 2/20/2003 9:21AM
  Basic session test
*/
session_start();
echo(pwhadda!)
?

And it results in

Fatal error: session_start() [function.session-start]: Failed to initialize
session module in ... on line 6

My php.ini has the following set (I've tried with both settings) :

;session.save_path = C:/TEMP/phpsessions
session.save_path = D:\temp\php

Any thoughts?

thanks,
neko

[PHP] Failed to initialize session module

[derek fong]

Hello,

I am trying to get session data written to a MySQL table using 
set_session_save_handler(), but am getting the following error when I 
issue session_register(varname) on a page:

Fatal error: Failed to initialize session module in 
/Library/WebServer/Documents/VirtualHosts/www/admin/en/login.php on 
line 4

I have set session.save_handler to user and session.save_path to 
mysql://USER:PASS@localhost/DB in my php.ini file.  File-based 
sessions seem to work fine with session.save_handler set to files and 
session.save_path to /tmp.  I am using the following code as my save 
handler (taken from Web Application Development With PHP 4.0 by 
Tobias Ratschiller and Till Gerken):

?php
$sess_mysql = array();
$sess_mysql[open_connection] = true;
$sess_mysql[hostname] = localhost;
$sess_mysql[user] = USER;
$sess_mysql[password] = PASS;
$sess_mysql[db] = DB;
$sess_mysql[table] = sessions;

function sess_mysql_open($save_path, $sess_name)
{
global $sess_mysql;

if ($sess_mysql[open_connection])
{
$link = mysql_pconnect($sess_mysql[hostname], 
$sess_mysql[user],
$sess_mysql[password]) or die(mysql_error());
}

return (true);
}


function sess_mysql_read($sess_id)
{
global $sess_mysql;
$result = mysql_db_query($sess_mysql[db], SELECT data FROM 
.$sess_mysql[table] . WHERE id = 
'$sess_id') or
die(mysql_error());

if (mysql_num_rows($result) == 0)
{
return ();
}

$row = mysql_fetch_array($result);
mysql_free_result($result);

return ($row[data]);
}


function sess_mysql_write($sess_id, $val)
{
global $sess_mysql;

$result = mysql_db_query($sess_mysql[db], REPLACE INTO 
.$sess_mysql[table] . VALUES 
('$sess_id', '$val', null)) or
die(mysql_error());

return (true);
}


function sess_mysql_destroy($sess_id)
{
global $sess_mysql;

$result = mysql_db_query($sess_mysql[db], DELETE FROM 
.$sess_mysql[table] . WHERE id = 
'$sess_id') or
die(mysql_error());

return (true);
}


function sess_mysql_gc($max_lifetime)
{
global $sess_mysql;

$old = time() - $max_lifetime;

$result = mysql_db_query($sess_mysql[db], DELETE FROM 
.$sess_mysql[table] . WHERE 
UNIX_TIMESTAMP(t_stamp)  $old) or
die(mysql_error());

return (true);
}

session_set_save_handler(sess_mysql_open, , sess_mysql_read, 
sess_mysql_write,
sess_mysql_destroy, sess_mysql_gc);
?


I have also tried Sam Johnston's PEAR Custom Session Handler for PHP4 
(http://sourceforge.net/projects/pearsession/), but I get the same 
error.  Like I said, file-based sessions are working fine, but any 
custom handler bombs with the error I noted above.  This is all 
running under Mac OS X 10.1.1, PHP 4.0.6 using the PEAR DB libraries 
(among others) and MySQL 3.23.43.

What could be causing the error?  I've searched and searched but 
can't seem to find any answers.  Thanks in advance,

-f
