The log write method provided by YII:

1, Yii::getlogger ()->log ($message, $level, $category = ' application ')

2, Yii::trace ($message, $category = ' application ');

3, Yii::error ($message, $category = ' application ');
4, Yii::warning ($message, $category = ' application ');
5, Yii::info ($message, $category = ' application ');


Configuration:
     /config/web.php

  Components->log

Default configuration:

'Log'= [            'TraceLevel'= Yii_debug?3:0,            'Targets'= [                [                    'class'='Yii\log\filetarget',                    'levels'= ['Error','Warning'],                ],            ],        ],

The configuration is now modified as follows:

'Log'= [            'TraceLevel'= Yii_debug?3:0,            'Targets'= [                [                    'class'='Yii\log\filetarget',                    'levels'= ['Error','Warning','Info','Trace'],                ],                [                    'class'='Yii\log\filetarget',                    'levels'= ['Info'],                    'Categories'= ['RHYTHMK'],                    'LogFile'='@app/runtime/logs/mylog/requests.log',                    'MaxFileSize'=1024x768*2,                    'Maxlogfiles'= -,                ],            ],        ],

Output log:

Yii::getlogger ()->log ("Start writing custom Log", Logger::level_error);

Yii::trace ("Trace, logging when developing and debugging");

Yii::error ("error log");

Yii::warning ("Warning, warning message");

Yii::info ("info, record operation Tips");
