An article to talk about the error reporting level of ThinkPHP

ThinkPHP is a PHP development framework for web application development. It uses modular, MVC, ORM, object-oriented and other development technologies to provide developers with a fast, efficient, safe and convenient development environment. However, during the development process using ThinkPHP, developers may encounter various error reports, of which error level is a very important concept.

First, let’s take a look at ThinkPHP’s error reporting levels, which are divided into the following categories:

1. ERROR: A serious error that will cause the program to fail.
2. WARNING: Warning, it does not affect the normal operation of the program, but you need to pay attention.
3. NOTICE: Notification, can be ignored and does not affect program operation.
4. DEBUG: debugging information, used to troubleshoot code problems.
5. SQL: SQL statement, often used to debug SQL statement problems.

The above are the five error levels of ThinkPHP. By default, ThinkPHP's error reporting levels are ERROR, WARNING, and NOTICE, which means only three levels of errors: serious, warning, and notification. If you need to debug the program, you can set the error reporting level to DEBUG and SQL.

In the development process, debugging is a very important part. When the program reports an error, the error code can be quickly located and repaired through the error message. After development is completed, if debugging information is not needed, the error reporting level can be set to ERROR, WARNING, and NOTICE. This can reduce unnecessary information interference and improve program operation efficiency.

In addition to setting the error level, ThinkPHP also provides the Trace debugging tool, which can display the complete call stack information and related variable values ​​​​when the program reports an error, making it easier for developers to quickly locate the problem. In a production environment, the Trace debugging tool needs to be turned off to ensure program security and performance.

In short, error reporting level is a very important concept in the development process. When using ThinkPHP for development, you need to set different error reporting levels according to the actual situation so that problems can be quickly located and repaired. At the same time, the Trace debugging tool is also a very useful tool that can help developers quickly troubleshoot problems and improve development efficiency.
