Yii2.0中文开发向导——自定义日志文件写日志头部引入log类use yii\log\FileTarget;
$time = microtime(true);$log = new FileTarget();$log->logFile = Yii::$app->getRuntimePath() . '/logs/zhidemy.com.log';//文件名自定义$log->messages[] = ['test',1,'application',$time];$log->export();这样基本就能写出来了，先看一下$log->message的类描述信息/** [0] => message (mixed, can be a string or some complex data, such as an exception object)* [1] => level (integer)* [2] => category (string)* [3] => timestamp (float, obtained by microtime(true))* [4] => traces (array, debug backtrace, contains the application code call stacks)*/传递参数按照这些信息进行传递就可以了。最后记住重要的一点$log->messages[] 别忘了加[]具体可查看Target类
