Detailed Description

getID3() by James Heinrich info@.nosp@m.geti.nosp@m.d3.or.nosp@m.g //

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
