• $key is a string representing the Logger key.

Use

Load a shared Logger instance.

• $key is a string representing the Logger key, and will default to Log::DEFAULT.

Loggers

You can load a specific logger by specifying the className option of the $config variable above.

Custom loggers can be created by extending \Fyre\Log\Logger, ensuring all below methods are implemented.

Can Handle

Determine if a log level can be handled.

• $level is a number indicating the log level.

By default, this method will return true if the $level is below or equal to the threshold defined in the logger config, otherwise false.

Handle

Handle a message log.

• $type is a string representing the type of log.
• $message is a string representing the log message.

File

The File logger can be loaded using custom configuration.

• $key is a string representing the logger key.
• $options is an array containing configuration options.
  • className must be set to \Fyre\Log\Handlers\FileLogger.
  • dateFormat is a string representing the date format, and will default to "Y-m-d H:i:s".
  • threshold is a number representing the log threshold, and will default to 0.
  • suffix is a string representing the filename suffix, and will default to null.
  • path is a string representing the directory path, and will default to "/var/log".
  • extension is a string representing the file extension, and will default to "log".
  • maxSize is a number representing the maximum file size before log rotation, and will default to 1048576.

Logging

Generally, logging is done by calling the static methods of the Log class.

This will call the canHandle method of all defined logger configs, and if that returns true then the handle method will also be called.

The default log levels are shown below (in order of severity).

• $message is a string representing the log message.
• $data is an array containing data to insert into the message string.

There are default placeholders that can also be used in log messages:

• {post_vars} will be replaced with the $_POST data.
• {get_vars} will be replaced with the $_GET data.
• {server_vars} will be replaced with the $_SERVER data.
• {session_vars} will be replaced with the $_SESSION data.
• {backtrace} will be replaced with the backtrace.

See the MessageFormatter::formatMessage method for details about message formatting.
