// -------------------------
// log
//
// main log class for parsing text logs and processing the data
// must be used with a log processor descendent
//
// -------------------------

//
// add other regular expression patterns and matches arrays here to match other log formats
// the $patterns[$key] (eg. apacheDefault) should be passed to the parse() function as the
// $type parameter
//

//
// the matches here, represent the $matches index from preg_match for the pattern

// -------------------------

// -------------------------

//
// very basic class to output data in a very simple format

// -------------------------

// -------------------------
// log_mysql
//
// mysql class for storing parsed log data in a table
// in my tests, this script processes ~1500-4000 rows/second
//
// -------------------------
// Example table structure for apache:
//
// CREATE TABLE `log` (
// `id` int(11) NOT NULL auto_increment,
// `ip` varchar(255) NOT NULL default '',
// `identd` varchar(255) NOT NULL default '',
// `auth` varchar(255) NOT NULL default '',

// `month` varchar(255) NOT NULL default '',
// `year` int(8) NOT NULL default '0',
// `time` varchar(255) NOT NULL default '',
// `request` text NOT NULL,
// `http_version` varchar(255) NOT NULL default '',
// `response_code` int(8) NOT NULL default '0',
// `size` int(11) NOT NULL default '0',
// `referrer` text NOT NULL,
// `navigator` text NOT NULL,
// PRIMARY KEY (`id`)
// ) ENGINE=MyISAM DEFAULT CHARSET=latin1
//
// and the example $fields array to complement it:
//
// $fields => array(
// // key in $data field name in table
// 'ip' => 'ip',
// 'identd' => 'identd',
// 'auth' => 'auth',
// 'day' => 'day',
