How to enable error prompts in yii

When using the YII framework for development, you may encounter an error and you may not know where the error is after looking for it for a long time. If the error message prompt is turned on, it will be obvious. I know where the mistake is.

But we’d better put the error message when accessing index-test.php instead of prompting when accessing index.php. How should we deal with it?

First of all, we need to open the error message prompt in index-test.php. We need to add the following two lines of code

ini_set('display_errors', 'On');
error_reporting(E_ALL & ~E_NOTICE);

Then find the following code in main.php under config

'log'=>array(
'class'=>'CLogRouter',
'routes'=>array(
array(
'class'=>'CFileLogRoute',
'levels'=>'error, warning',
),
// uncomment the following to show log messages on web pages
// array(
// 'class'=>'CWebLogRoute',
// ),
),
),

But we only need to reduce the code and put it under test.php. The reduced code is as follows

'log'=>array(
'routes'=>array(
// uncomment the following to show log messages on web pages
array(
'class'=>'CWebLogRoute',
),
),
),

However, this code cannot be placed anywhere. , it must be placed in the array 'components'=>array(). Next, visit index.php and index-test.php to see the effect
