/** | ||
* 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'; | ||
* $info1 = $getID3->analyze('file1.flac'); | ||
* $info2 = $getID3->analyze('file2.wv'); | ||
* | ||
* | ||
* Supported Cache Types | ||
* | ||
* SQL Databases: (use extension.cache.mysql) | ||
* | ||
* cache_type cache_options | ||
* ------------------------------------------------------------------- | ||
* mysql host, database, username, password | ||
* | ||
* | ||
* 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) | ||
* | ||
* PHP must have write access to both dbm_filename and lock_filename. | ||
* | ||
* | ||
* Recommended Cache Types | ||
* | ||
* Infrequent updates, many reads any DBM | ||
* Frequent updates mysql | ||
