*
* DESCRIPTION:
* Generate a simple calendar that can integrate seamlessly into any system with minimal
* installation. You must be running be running PHP 4 at the minimal.
*
*
* INSTALLATION:
* 1. Save the code in a file call calender8.php. Then Insert this file into anywhere where
* you want the calendar to appear. Use:
*
* require_once('calender8.php');
*
* or if you save the file elsewhere, require_once('dir_path/calender8.php')
*
*
*
*
*
*
*
*
* 2. Create a table in your database. If you are using your own table, you need to map the fields
* appropriately.
*
* CREATE TABLE `calendar` (
* `id` INT NOT NULL AUTO_INCREMENT ,
`* day` VARCHAR( 2 ) NOT NULL ,
* `month` VARCHAR( 2 ) NOT NULL ,
* `year` VARCHAR( 4 ) NOT NULL ,
* `link` VARCHAR( 255 ) NOT NULL ,
* `desc` TEXT NOT NULL ,
* PRIMARY KEY ( `id` )
* );
*
* 3. Configure the db and path access below. Use any db of your choice. You can also configure
* the CSS to change the look and feel of the calendar.
