/**
* This is a caching extension for getID3(). It works the exact same
* way as the getID3 class, but return cached information very fast
*
* Example: (see also demo.cache.mysql.php in /demo/)
*
* Normal getID3 usage (example):
*
* require_once 'getid3/getid3.php';
* $getID3 = new getID3;
* $getID3->encoding = 'UTF-8';
* $info1 = $getID3->analyze('file1.flac');
* $info2 = $getID3->analyze('file2.wv');
*
* getID3_cached usage:
*
* require_once 'getid3/getid3.php';
* require_once 'getid3/getid3/extension.cache.mysqli.php';
* // 5th parameter (tablename) is optional, default is 'getid3_cache'
* $getID3 = new getID3_cached_mysqli('localhost', 'database', 'username', 'password', 'tablename');
* $getID3->encoding = 'UTF-8';
* $info1 = $getID3->analyze('file1.flac');
* $info2 = $getID3->analyze('file2.wv');
*
*
* Supported Cache Types (this extension)
*
* SQL Databases:
*
* cache_type cache_options
* -------------------------------------------------------------------
* mysqli host, database, username, password
*
*
* DBM-Style Databases: (use extension.cache.dbm)
*
* cache_type cache_options
* -------------------------------------------------------------------
* gdbm dbm_filename, lock_filename
* ndbm dbm_filename, lock_filename
* db2 dbm_filename, lock_filename
* db3 dbm_filename, lock_filename
* db4 dbm_filename, lock_filename (PHP5 required)
*
* PHP must have write access to both dbm_filename and lock_filename.
*
*
* Recommended Cache Types
*
* Infrequent updates, many reads any DBM
* Frequent updates mysqli

Note: purposely doing the less-pretty (and probably a bit slower) method of using string of bits rather than bitwise operations.
Mostly because PHP 32-bit doesn't handle unsigned integers well for bitwise operation.
Also the MPEG stream is designed as a bitstream and often doesn't align nicely with byte boundaries.
