定制php4的session功能(6) * this header information. If you make any modifications or improvements,
* please send them via email to Ying Zhang <ying@zippydesign.com>.
*
* ------------------------------------------------------------------------
* DESCRIPTION:
* ------------------------------------------------------------------------
* This library tells the PHP4 session handler to write to a MySQL database
* instead of creating individual files for each session.
*
* Create a new database in MySQL called "sessions" like so:
*
* CREATE TABLE sessions (
* sesskey char(32) not null,
* expiry int(11) unsigned not null,
* value text not null,
* PRIMARY KEY (sesskey)
* );
*
* ------------------------------------------------------------------------
* INSTALLATION:
* ------------------------------------------------------------------------
* Make sure you have MySQL support compiled into PHP4. Then copy this
* script to a directory that is accessible by the rest of your PHP
* scripts.
*
* ------------------------------------------------------------------------
* USAGE:
* ------------------------------------------------------------------------
* Include this file in your scripts before you call session_start(), you
* don't have to do anything special after that.
