ThinkPHP is a very popular PHP open source framework. Its built-in debug mode trace function can very conveniently help us locate problems. However, in a production environment, we usually turn off debug mode for security and performance reasons. This article will introduce how to turn off the trace debugging mode in ThinkPHP.

Why should we turn off trace mode?

Trace mode is ThinkPHP’s own debugging mode. You can easily view relevant information of the current request at the bottom of the page, such as request parameters, SQL statements, etc., which is very helpful for problem location. However, in a production environment, we do not want this sensitive information to be leaked, thus affecting the security of the system. In addition, debugging mode will also bring certain performance losses, so it is necessary for us to turn it off.

How to turn off trace mode?

ThinkPHP enables trace mode by default. We can turn off trace mode by setting the app_debug parameter.

In the app.php file under the config directory, we can find the following configuration:

//?是否開啟應用調(diào)試模式
'app_debug'?=>?env('app_debug',?true),

Place app_debug The value of is set to false to turn off the trace mode. The code is as follows:

//?是否開啟應用調(diào)試模式
'app_debug'?=>?false,

In addition to turning off the trace mode by modifying the configuration file, we can also turn off the trace mode in the application's controller (usually the base controller) add the following method:

/**
?*?構造函數(shù)
?*
?*?關閉調(diào)試模式
?*/
public?function?__construct()
{
????parent::__construct();

????//?開發(fā)環(huán)境下，不關閉調(diào)試
????if?(config('app_debug'))?{
????????return;
????}

????//?關閉調(diào)試
????config('app_trace',?false);
????config('app_debug',?false);
}

This method will be called when the controller is initialized. If app_debug is configured as false, it will Turn off trace mode.

Summary

In a production environment, in order to ensure the security and performance of the system, it is necessary to turn off the trace debugging mode. We can easily achieve this by modifying the configuration file or adding a shutdown method in the base controller. Of course, in the development environment, we can still enjoy the convenience brought by trace mode to locate problems faster.
