Thanks for trying out retweeter. 

NOTE: Twitter's user ids and tweet ids have grown to the point where the
20 character limit on the PostId table is insufficient. (The symptom of
this problem is that ReTweeter will start failing to recognize existing
tweets, and will start to create duplicates in the database, which it
will then try to retweet, resulting in 403 erros.) Running the following
query in your MySQL environment will fix this problem. 

Assuming you already have a database from version 1.1, you'll need to
update your PostId column, and it's a good idea to update your
PlainPostID column as well, just to give breathing room. 

TO UPDATE YOUR PostId and PlainPostID COLUMNs TO 30 CHARS WIDE, RUN THIS SQL:

-----
ALTER TABLE `tweet` MODIFY `PostId` varchar(30);
ALTER TABLE `tweet` MODIFY `PlainPostID` varchar(30);
-----

If you've used a version prior to 1.1, you will need to make database
changes to update your tables. 

IF AND ONLY IF YOU HAVE EXISTING DATABASE FROM VERSIONS < 1.1, RUN THIS SQL:
----------------------

CREATE TABLE `conf` (
  `meta_key` varchar(4) default NULL,
  `meta_value` varchar(32) default NULL,
  `CreatedDate` timestamp NOT NULL default CURRENT_TIMESTAMP,
  `ModifiedDate` timestamp NOT NULL default '0000-00-00 00:00:00',
  PRIMARY KEY  (`meta_key`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8;

ALTER TABLE `tweet` ADD COLUMN `PlainPostID` varchar(20) default NULL;
 
----------------------

All necessary configuration is at the top of the retweeter.php file. Set 
$username and $password to the twitter account username and pass, then
set all the DB info. 

You'll also need to register your app over at Twitter, and then set the 
appropriate fields in the config file - there are four in total (2 relate to
the app itself, 2 to the specific twitter account it will need to access). 

You'll need to setup the database directly, and create
tables named "log", "tweet", and "conf". (see SQL below). 

Retweeter depends on PHP5, since it uses SimpleXML to parse what Twitter 
returns. 

It expects to be run from the command line, on a cron job - remember that
the Twitter API is time-limited. I use a setting of every 2 minutes, which
is pretty frequent but stays within the API bounds.

Here's the SQL for the tables:

CREATE TABLE `log` (
  `Id` int(11) NOT NULL auto_increment,
  `Status` int(11) default NULL,
  `CreatedDate` timestamp NOT NULL default CURRENT_TIMESTAMP,
  PRIMARY KEY  (`Id`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8 ;

CREATE TABLE `tweet` (
  `Id` int(11) NOT NULL auto_increment,
  `PostId` varchar(30) default NULL,
  `User` varchar(100) default NULL,
  `Tweet` varchar(250) default NULL,
  `CreatedDate` timestamp NOT NULL default CURRENT_TIMESTAMP,
  `ModifiedDate` timestamp NOT NULL default '0000-00-00 00:00:00',
  `Tweeted` datetime default NULL,
  `PlainPostID` varchar(30) default NULL,
  PRIMARY KEY  (`Id`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8 ;

CREATE TABLE `conf` (
  `meta_key` varchar(4) default NULL,
  `meta_value` varchar(32) default NULL,
  `CreatedDate` timestamp NOT NULL default CURRENT_TIMESTAMP,
  `ModifiedDate` timestamp NOT NULL default '0000-00-00 00:00:00',
  PRIMARY KEY  (`meta_key`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8 ;
