Create this table in your database (syntax might vary depending on your db): + + create table sessions ( + SESSKEY char(32) not null, + EXPIRY int(11) unsigned not null, + EXPIREREF varchar(64), + DATA text not null, + primary key (sesskey) + ); + + For oracle: + create table sessions ( + SESSKEY char(32) not null, + EXPIRY DECIMAL(16) not null, + EXPIREREF varchar(64), + DATA varchar(4000) not null, + primary key (sesskey) + ); + + + 2. Then define the following parameters. You can either modify + this file, or define them before this file is included: + + $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'; + $ADODB_SESSION_TBL = 'sessions' + + 3. Recommended is PHP 4.1.0 or later. There are documented + session bugs in earlier versions of PHP. + + 4. If you want to receive notifications when a session expires, then + you can tag a session with an EXPIREREF, and before the session + record is deleted, we can call a function that will pass the EXPIREREF + as the first parameter, and the session key as the second parameter. + + To do this, define a notification function, say NotifyFn: + + function NotifyFn($expireref, $sesskey) + { + } + + Then you need to define a global variable $ADODB_SESSION_EXPIRE_NOTIFY. + This is an array with 2 elements, the first being the name of the variable + you would like to store in the EXPIREREF field, and the 2nd is the + notification function's name. + + In this example, we want to be notified when a user's session + has expired, so we store the user id in the global variable $USERID, + store this value in the EXPIREREF field: + + $ADODB_SESSION_EXPIRE_NOTIFY = array('USERID','NotifyFn'); + + Then when the NotifyFn is called, we are passed the $USERID as the first + parameter, eg.
