- Public Member Functions inherited from Monolog\Handler\AbstractProcessingHandler
 handle (array $record)
 {Handles a record.All records may be passed to this method, and the handler should discard those that it does not want to handle.The return value of this function controls the bubbling process of the handler stack. Unless the bubbling is interrupted (by returning true), the Logger class will keep on calling further handlers in the stack with a given log record.
Parameters
array$recordThe 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 $record)
 {Checks whether the given record will be handled by this handler.This is mostly done for performance reasons, to avoid calling processors for nothing.Handlers should still check the record levels within handle(), returning false in isHandling() is no guarantee that handle() will not be called, and isHandling() might not be called for a given record.
Parameters
array$recordPartial log record containing only a level key
Returns
Boolean

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
int$maxFilesThe maximal amount of files to keep (0 means unlimited)
int$levelThe minimum logging level at which this handler will be triggered
Boolean$bubbleWhether the messages that are handled can bubble up the stack or not
int | null$filePermissionOptional file permissions (default (0644) are only for owner read/write)
Boolean$useLockingTry to lock log file before doing any writes
