- * This is a caching extension for getID3(). It works the exact same
20
- * way as the getID3 class, but return cached information much faster
21
- *
22
- * Normal getID3 usage (example):
23
- *
24
- * require_once 'getid3/getid3.php';
25
- * $getID3 = new getID3;
26
- * $getID3->encoding = 'UTF-8';
27
- * $info1 = $getID3->analyze('file1.flac');
28
- * $info2 = $getID3->analyze('file2.wv');
29
- *
30
- * getID3_cached usage:
31
- *
32
- * require_once 'getid3/getid3.php';
33
- * require_once 'getid3/extension.cache.sqlite3.php';
34
- * // all parameters are optional, defaults are:
35
- * $getID3 = new getID3_cached_sqlite3($table='getid3_cache', $hide=FALSE);
36
- * $getID3->encoding = 'UTF-8';
37
- * $info1 = $getID3->analyze('file1.flac');
38
- * $info2 = $getID3->analyze('file2.wv');
39
- *
40
- *
41
- * Supported Cache Types (this extension)
42
- *
43
- * SQL Databases:
44
- *
45
- * cache_type cache_options
46
- * -------------------------------------------------------------------
47
- * mysql host, database, username, password
48
- *
49
- * sqlite3 table='getid3_cache', hide=false (PHP5)
50
- *
51
-
52
- *** database file will be stored in the same directory as this script,
53
- *** webserver must have write access to that directory!
54
- *** set $hide to TRUE to prefix db file with .ht to pervent access from web client
55
- *** this is a default setting in the Apache configuration:
56
-
57
- # The following lines prevent .htaccess and .htpasswd files from being viewed by Web clients.
58
-
59
- <Files ~ "^\.ht">
60
- Order allow,deny
61
- Deny from all
62
- Satisfy all
63
- </Files>

68
- * DBM-Style Databases: (use extension.cache.dbm)
69
- *
70
- * cache_type cache_options
71

72
- * gdbm dbm_filename, lock_filename
73
- * ndbm dbm_filename, lock_filename
74
- * db2 dbm_filename, lock_filename
75
- * db3 dbm_filename, lock_filename
76
- * db4 dbm_filename, lock_filename (PHP5 required)
77
- *
78
- * PHP must have write access to both dbm_filename and lock_filename.
79
- *
80
- * Recommended Cache Types
81
- *
82
- * Infrequent updates, many reads any DBM
83
- * Frequent updates mysql
84
- ********************************************************************************
85
- *
86
- * IMHO this is still a bit slow, I'm using this with MP4/MOV/ M4v files
87
- * there is a plan to add directory scanning and analyzing to make things work much faster
