详情
设置一个索引数组，日志组为键文件名为值. 如果设置，该日志组的 输出将转到设置的文件里而不是常规的. 对生产环境下选择性日志非常有用.

Log destinations may be one of the following:


 * false to completely remove from the output, including from $wgDebugLogFile.
 * string values specifying a filename or URI.
 * associative array with keys:
 * 'destination' desired filename or URI.
 * 'sample' an integer value, specifying a sampling factor (optional)
 * 'level' A \Psr\Log\LogLevel constant, indicating the minimum level log (optional, since 1.25)

When  is set to a non-default value,   will probably be ignored, and the method of configuring log files will be determined by whatever logging system is invoked by.

Example
This example logs debug messages of group "ConfirmEditExtension" to "debug-ext_confirmedit.log" and those of group "SpamRegex" to "debug-spam.log".
