lcLogger for PHP

lcLogger is a simple php class to log messages to a file or database (MySql or Mongodb)

Requierements

• at least PHP5.4
• Mysqli if you want to use MySql
• MongoClient (PHP5) or MongoDBManager(PHP7) if you use MongoDB

Useage

just include the file and init the logger

<?php
include_once "lcLogger/lcLogger.php";

lcLogger::Init("File",["File"=>"Log.log"]);

// set a loglevel
lcLogger::SetLogLevel("Debug");

// log a message
lcLogger::Warn("Warn message",[1337=>"test"]);

Loglevels

Possible loglevels are:

• critical
• warn
• info
• debug

Set the loglevel with lcLogger::SetLogLevel($sLevel); if you set an invalid level, the function will return false and the level will be set to warn. If you don't set any loglevel, the defaul will be warn.

To log a message to a level use these functions

lcLogger::Critical("Critical message");
lcLogger::Warn("Warn message");
lcLogger::Info("Info message");
lcLogger::Debug("Debug message");

all these functions are taking a second parameter that could be anything. It will be converted to a String and is added to the logmessage:

lcLogger::Critical("Critical message",["User"=>"123","Host"=>"321"]);
lcLogger::Debug("Debug message",$oObjectToDebug);

Logging to file

Use lcLogger::Init("File",$aOption); to init the logger for file-logging. When using files for logging make sure that nobody can access the files from outside (deny *.log via htaccess eg.)

Options (both are optional) are:

• File -> Default is `date("my")" ".log" extension is added within the function
• Format -> Default is "%date%\t%level%\t%ip%:%method%\t%uri%:%source%\t%message%\r\n"

<?php
include_once "lcLogger/lcLogger.php";

$aOptions = [
    "File"      => "mylog-".date("my"),
    // use spaces instead of tabs
    "Format"    => "%date% %level% %ip%:%method% %uri%:%source% %message%\r\n"
];
lcLogger::Init("File",$aOptions);

lcLogger::SetLogLevel("warn");

lcLogger::Critical("Critical message");

Logging to MySql

Use lcLogger::Init("MySql",$aOption); to init the logger to save the log in a MySql database. Options are: (Requiered)

• Host => MySql Host, default is "localhost"
• Database => Databasename in MySql, default is "Log"

    "Password"  => "PASSWORD",
    "Database"  => "Log2017",
    "Table"     => date("my")
];
lcLogger::Init("MySql",$aOptions);

lcLogger::SetLogLevel("warn");

lcLogger::Critical("Critical message");

Logging to MonogDB

Use lcLogger::Init("MongoDB",$aOption); to init the logger to save the log in a MongoDB database.
