PVLog is used to write information to a log for record keeping.
The logs that can be recorded is up to the developer. The class can be overridden with Adapters to do things like write to syslog or external logging services.
Example:
//Initialize The class
PVLog::init();
//Write various logs with different priority levels
PVLog::writeLog('Warning', 'Illegal Access By User');
PVLog::writeLog('High Alert', 'System Almost Out Of Memory');
PVLog::writeLog('Low', 'Page Not Found');
//Get the logs with a high priority level
$logs = PVLog::readLog('High Alert');| package |
