/**
|

* This is a caching extension for getID3(). It works the exact same
|
||||
* way as the getID3 class, but return cached information very fast
|
||||
*
|
||||
* Example:
|
||||
*
|
||||
* 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.dbm.php';
|
||||
* $getID3 = new getID3_cached('db3', '/tmp/getid3_cache.dbm',
|
||||
* '/tmp/getid3_cache.lock');

* $getID3->encoding = 'UTF-8';

* $info2 = $getID3->analyze('file2.wv');
|

*
|

*
|

|

*
|

* SQL Databases: (use extension.cache.mysql)
|

*
|

* cache_type cache_options
|

*
|

* DBM-Style Databases: (this extension)
|

* 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)
|

*
|

/**
|
||||
* 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.mysql.php';
|
||||
* // 5th parameter (tablename) is optional, default is 'getid3_cache'
|
||||
* $getID3 = new getID3_cached_mysql('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
|
||||
* -------------------------------------------------------------------
|
||||
* mysql 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 mysql
