How to turn off undefined variable prompts in thinkphp

In the development of ThinkPHP, we usually encounter the problem of undefined variables. At that time, ThinkPHP provided some methods to solve this problem. In this article, we will discuss how to turn off undefined variable prompts.

1. Why undefined variables appear

Undefined variables usually appear in the following situations:

1. Variables are spelled incorrectly.
2. Variable has not been declared or assigned a value.
3. The variable scope is incorrect.

In order to turn off undefined variable prompts, we can modify the php.ini file or configure it in the application. Below are detailed instructions for both methods.

Open the php.ini file and find the error_reporting configuration item in it. Change its value to the following code:

error_reporting = E_ALL & ~E_NOTICE & ~E_STRICT

This configuration will turn off the prompt for undefined variables.

2. Configure in the application

If you don’t want to modify the php.ini file, you can configure it in the ThinkPHP application. First, find the following code in the public/index.php file:

define('APP_DEBUG', true);

Change the value of APP_DEBUG to false. This turns off all debugging information, including undefined variable prompts.

In addition to turning off all debugging information, we can also turn off undefined variables. The following code can be added to the config.php file:

'display_not_found_error' => false,

'trace_exception' => false,

The above configuration will be Turn off undefined variable prompts in the application.
