Database functionality is hard-coded into the class. The class assumes the following database information:
CREATE TABLE `blacklisted` (
`email` varchar(75) NOT NULL default '',
PRIMARY KEY (`email`)
) TYPE=MyISAM;
CREATE TABLE `subscribers` (
`id` bigint(20) NOT NULL auto_increment,
`email` varchar(75) NOT NULL default '',
`name` varchar(75) NOT NULL default '',
`active` smallint(1) NOT NULL default '0',
`blacklisted` smallint(1) NOT NULL default '0',
`timestamp` bigint(20) NOT NULL default '0',
PRIMARY KEY (`id`)
) TYPE=MyISAM;
CREATE TABLE `subscriptions` (
`id` bigint(20) NOT NULL auto_increment,
`subscriberid` bigint(20) NOT NULL default '0',
`topicid` bigint(20) NOT NULL default '0',
`active` smallint(1) NOT NULL default '0',
PRIMARY KEY (`id`)
) TYPE=MyISAM;
CREATE TABLE `topics` (
`id` bigint(20) NOT NULL auto_increment,
`topic` varchar(50) NOT NULL default '',
`description` text NOT NULL,
PRIMARY KEY (`id`)
) TYPE=MyISAM
