Configure the 404 page for the PHP project in a unified manner (including the yii Framework)

: This article describes how to set up the 404 page for PHP projects in a unified manner (including the yii Framework). If you are interested in the PHP Tutorial, refer to it. 1. create a custom 404 page using Apache + PHP.

First, you can use Apache's. htaccess to define a file that does not exist,

The method is to create a new. htaccess, and add ErrorDocument 404/404 .php (/404. php is a custom 404 page) at the beginning of. htaccess ).

2. set it in yii Framework

If the requested page does not exist, yii will throw a CHttpException exception with the exception code 404. how can I handle this exception in yii? there are three methods:
1. you don't need to do anything. yii will handle it by itself.
When this type of exception is thrown, yii renders the errorxxx. php (error404.php) template file under framework/view/by default.
2. create errorxxx. php under protected/views/system, and yii will render the file.
3. configure an exception processor
Add the following configuration in the configuration file main. php and set the Exception Handling Controller to site/error.

'errorHandler'=>array(              // use 'site/error' action to display errors              'errorAction'=>'site/error',          ),  

Then add the error controller in SiteController. php:

public function actionError()      {          if($error=Yii::app()->errorHandler->error)          {print_r($error);              if(Yii::app()->request->isAjaxRequest)                  echo $error['message'];              else                  $this->render('error', $error);          }      }  

Finally, add the error. php template file under view/site:

 pageTitle=Yii::app()->name . ' - Error';  $this->breadcrumbs=array(      'Error',  );  ?>    Error 
     
  
    
  

The above introduces the PHP project unified settings 404 page (including the yii Framework), including the content, hope to be helpful to friends interested in PHP tutorials.
