KLogger
KLogger is a simple-to-use PHP text file logging class. It was made to have basic logging functionality, be lightweight, and be safe to use (permissions-wise). The reason for its creation is two-fold: I needed a simple logging class with priority hierarchies ( Debug, Info, Warn, etc .. ), and I couldn’t find it on the internet.
For small web applications or development sites, the use of logging libraries isn’t necessary. All you need is something like KLogger, a simple logging class.
KLogger supports:
- Safe logging (no PHP errors due to permissions)
- Smart file management (closing up resources)
- Priority heirarchies (OFF, DEBUG, INFO, WARN, ERROR, and FATAL)
Basic usage would look like this:
require_once 'KLogger.php'; ... $log = new KLogger ( "log.txt" , KLogger::DEBUG ); // Do database work that throws an exception $log->LogError("An exception was thrown in ThisFunction()"); // Print out some information $log->LogInfo("Internal Query Time: $time_ms milliseconds"); // Print out the value of some variables $log->LogDebug("User Count: $User_Count");
Using KLogger will eventually generate a log file that looks something like this one, which is the actual output from wpSearch, the Lucene based search plugin for wordpress. Tracking down a couple outstanding bugs became much easier once I started using KLogger.
If you happen to be wondering what that log reader is, it’s KTail, a yet-to-be-released log “tailer” written in C#. It is multithreaded, tabbed, and super-useful for reading log files which get updated frequently. It displays changes to almost instantly. (It has yet to be tested on a gigantic log file, though). It’s a side project that doesn’t get a whole lot of attention.
