yii close error prompt

Change error_reporting in the php.ini file to: (Recommended learning: yii tutorial)

error_reporting=E_ALL & ~E_NOTICE

If you cannot operate the php.ini file, you can use the following method to add the following code to the page where you want to disable notice error prompts:

/* Report all errors except E_NOTICE */
error_reporting(E_ALL^E_NOTICE);

Use the above method, in YII protected/index.php

error_reporting(E_ALL^E_NOTICE);
// change the following paths if necessary
$yii=dirname(__FILE__).'/../framework/yii.php';
$config=dirname(__FILE__).'/protected/config/main.php';
 
//引用系统常量配置文件
require_once dirname(__FILE__).'/protected/config/constant.php';
 
// remove the following lines when in production mode
defined('YII_DEBUG') or define('YII_DEBUG',true);
// specify how many levels of call stack should be shown in each log message
defined('YII_TRACE_LEVEL') or define('YII_TRACE_LEVEL',3);
 
require_once($yii);
Yii::createWebApplication($config)->run();
