'log' => [
'tracelevel' => yii_debug ? 3 : 0,
'targets' => [
[
'class' => 'yii\log\filetarget',
'levels' => ['error', 'warning'],
],
'test' => [
'class' => 'yii\log\dbtarget',//datarget类
'logtable' => '{{%test_log}}',//日志表
'levels' => ['error', 'info', 'warning'],//日志等级
],
],
],
|
二：生成日志表
在项目目录下执行如下命令生成日志表
|
1
|
php yii migrate --migrationpath=@yii/log/migrations/
|
三：使用日志
在需要使用日志的地方使用
|
1
|
yii::info()
|
四：自定义dbtarget日志
1：首先创建一个自定义的日志表
(1)在项目目录下执行
|
1
|
php yii migrate/create create_test_log
|
(2)：在创建的migrate文件下编写创建数据库的迁移脚本

(3)：执行如下命令生成dbtarget日志表
|
1
|
php yii migrate

4：使用dbtarget日志
同样的使用yii::info来记录日志
到此这篇关于yii使用dbtarget实现日志功能的示例代码的文章就介绍到这了,更多相关yii dbtarget 日志内容请搜索服务器之家以前的文章或继续浏览下面的相关文章希望大家以后多多支持服务器之家！
