# Class LoggerAppenderDailyFile

An Appender that automatically creates a new logfile each day.

The file is rolled over once a day. That means, for each day a new file is created. A formatted version of the date pattern is used as to create the file name using the PHP_MANUAL#sprintf function.

This appender uses a layout.

# Configurable parameters:

- datePattern - Format for the date in the file path, follows formatting rules used by the PHP date() function. Default value: "Ymd".
- file - Path to the target file. Should contain a %s which gets substituted by the date.
- append - If set to true, the appender will append to the file, otherwise the file contents will be overwritten. Defaults to true.
