Latest version of ADODB is available at http://php.weblogs.com/adodb
======================================================================
This file provides PHP4 session management using the ADODB database
wrapper library.
Example
=======
GLOBAL $HTTP_SESSION_VARS;
include('adodb.inc.php');
#---------------------------------#
include('adodb-cryptsession.php');
#---------------------------------#
session_start();
session_register('AVAR');
$HTTP_SESSION_VARS['AVAR'] += 1;
print "
";
Installation
============
1. Create a new database in MySQL or Access "sessions" like
so:
create table sessions (
SESSKEY char(32) not null,
EXPIRY int(11) unsigned not null,
DATA text not null,
primary key (sesskey)
);
2. Then define the following parameters in this file:
$ADODB_SESSION_DRIVER='database driver, eg. mysql or ibase';
$ADODB_SESSION_CONNECT='server to connect to';
$ADODB_SESSION_USER ='user';
$ADODB_SESSION_PWD ='password';
$ADODB_SESSION_DB ='database';
$ADODB_SESSION_TBL = 'sessions'
3. Recommended is PHP 4.0.2 or later. There are documented
session bugs in
earlier versions of PHP.
