YII logging for debugging
提问by madi
In many cases, Xdebugis not suitable for debugging as it involves clicks to run to a particular line of codes. I want to use something that is similar to cakePHPdebug function for developers to output the value of a particular property of a class to the browser.
在许多情况下，Xdebug不适合调试，因为它涉及点击以运行到特定的代码行。我想使用类似于cakePHP调试功能的东西让开发人员将类的特定属性的值输出到浏览器。
I am using Yii frameworkand this is my configuration for the yii login the main.php:
我使用的Yii framework，这是我的配置yii log中main.php：
'log'=>array(
'class'=>'CLogRouter',
'routes'=>array(
array(
'class'=>'CFileLogRoute',
'levels'=>'trace, info, error, warning, vardump',
),
array(
'class'=>'CWebLogRoute',
'enabled' => YII_DEBUG,
'levels'=>'error, warning, trace, log, vardump',
'showInFireBug'=>true,
),
),
),
In one of my defined controller i put this code to test:
在我定义的控制器之一中，我将此代码用于测试：
Yii::log("CallFromUserController",'info', 'application');
However i don't see this being printed in the firebug. I used Chris's example:
但是我没有看到这个被打印在萤火虫中。我用克里斯的例子：

I finally managed to find out a solution:
我终于设法找到了解决方案：
In my main.php I did this:
在我的 main.php 我这样做了：
'log' => array(
'class' => 'CLogRouter',
'routes' => array(
array(
'class' => 'CFileLogRoute',
'levels' => 'trace, info, error, warning, vardump',
),
// uncomment the following to show log messages on web pages
array(
'class' => 'CWebLogRoute',
'enabled' => YII_DEBUG,
'levels' => 'error, warning, trace, notice',
'categories' => 'application',
'showInFireBug' => false,
),
),
),
In my controller I used this code:
在我的控制器中，我使用了以下代码：
$a = new array(1,2,3);
Yii::trace(CVarDumper::dumpAsString($a));
The Application Log is shown below in every page.
应用程序日志显示在每个页面的下方。

In Yii2
在 Yii2
Yii::trace(VarDumper::dumpAsString($array));
An example of customized log class is given below.
下面给出了自定义日志类的示例。
<?php
namespace app\helpers;
use Yii;
use yii\helpers\VarDumper;
class Log {
const LOG_CATEGORY_NAME = 'myLog';
public static function e($msg, $data) {
if (isset($data)) {
$msg .= " " . VarDumper::dumpAsString($data);
}
Yii::error($msg, self::LOG_CATEGORY_NAME);
}
}
Example:
例子：
Log.e("Copying the Estimate data failed. Model::getError(): ",
$model->getErrors());

You should add following lines to your protected/main.php file for debug:true mode. Trust work like a charm !
您应该将以下几行添加到您的 protected/main.php 文件以用于 debug:true 模式。信任工作就像一种魅力！
return array(
'preload' => array(
'debug',
),
'components' => array(
'debug' => array(
'class' => 'ext.yii2-debug.Yii2Debug',
),
'db' => array(
'enableProfiling' => true,
'enableParamLogging' => true,
),
),
);
