【MY_Log】自己写的MY_log库，支持自定义类别和子目录保存
本帖最后由 jiji262 于 2012-6-15 17:22 编辑I do some changes to Log library and now it has more fuure.
On github: https://github.com/jiji262/phpLauncher/blob/master/application/libraries/MY_Log.php
You can check my project here: https://github.com/jiji262/phpLauncher/
使用方法：
* Logging Class with catalog and sub_directories supported
*
* Usage:Change the catalogs config in application/config.php
* $config[‘mylog_cats’]= array(‘CAT1’,‘CAT2’,‘CAT3’);
* $config[‘mylog_sub_directories’]= true;
* Note: 1. Leaving this array blank will log ALL catalogs
*2. Without setting ‘mylog_cats; will default to use standard
*log threshold config item
*3. The log file will be saved to different directories under
*log_path which will be named “pathname-catname-date(‘Y-m-d’)-EXT”
*4.mylog_sub_directories can works even “mylog_cats” is not set
*
* Then you can use log_message(“CAT1”, “messages logged”); in you codes.
