Public Member Functions inherited from Monolog\Handler\AbstractProcessingHandler

handle (array $record)

{Handles a record.All records may be passed to this method, and the handler should discard those that it does not want to handle.The return value of this function controls the bubbling process of the handler stack. Unless the bubbling is interrupted (by returning true), the Logger class will keep on calling further handlers in the stack with a given log record.

Parameters

array $record The record to handle

Returns: Boolean true means that this handler handled the record, and that bubbling is not permitted. false means the record was either not processed or that this handler allows bubbling.

__construct ($level=Logger::DEBUG, $bubble=true)

isHandling (array $record)

{Checks whether the given record will be handled by this handler.This is mostly done for performance reasons, to avoid calling processors for nothing.Handlers should still check the record levels within handle(), returning false in isHandling() is no guarantee that handle() will not be called, and isHandling() might not be called for a given record.

Parameters

array $record Partial log record containing only a level key

Returns: Boolean

{Handles a set of records at once.

Detailed Description

Stores logs to files that are rotated every day and a limited number of files are kept.

This rotation is only intended to be used as a workaround. Using logrotate to handle the rotation is strongly encouraged when you can use it.

Constructor & Destructor Documentation

◆ __construct()

Monolog\Handler\RotatingFileHandler::__construct	(	$filename,
		$maxFiles = `0`,
		$level = `Logger::DEBUG`,
		$bubble = `true`,
		$filePermission = `null`,
		$useLocking = `false`
	)

Parameters

string	$filename
integer	$maxFiles	The maximal amount of files to keep (0 means unlimited)
integer	$level	The minimum logging level at which this handler will be triggered
Boolean	$bubble	Whether the messages that are handled can bubble up the stack or not
int \| null	$filePermission	Optional file permissions (default (0644) are only for owner read/write)
Boolean	$useLocking	Try to lock log file before doing any writes
