The best debugging tips in PHP development CMS programming 2

In the previous article, we have looked at some of the best debugging techniques in CMS programming for PHP development. In this article, we’ll continue to share some more in-depth tips to help you better debug your CMS code.

1. Use Xdebug for code debugging

Xdebug is a powerful PHP extension that can help you find out PHP programs without the need to single-step through the code. bug in. If you are an experienced PHP developer, it is recommended that you use Xdebug for code debugging. It supports debugging methods such as setting breakpoints, single-stepping, and code tracing. When using Xdebug, you can use Xdebug client tools, such as PhpStorm, Notepad and other tools.

2. Use PHPStorm for debugging

PHPStorm is a very powerful PHP integrated development environment (IDE). It integrates many development tools, plug-ins and toolkits, making PHP Development becomes simpler. Of course, PHPStorm also supports debugging. You can press F5 for single-step debugging, observe variable values, set breakpoints and other functions. At the same time, it can also be used with Xdebug to give you a better experience during the debugging process.

3. Use PHPUnit for unit testing

PHPUnit is a powerful PHP unit testing framework that can help you write high-quality PHP unit tests, thereby improving the efficiency of your code. quality. When unit testing, it can help you find potential errors and defects in your code. In addition to this, PHPUnit also provides an assertion library that can be used to verify the output of your code. This is very important to ensure code correctness in CMS development.

4. Use black box testing thinking for verification

Black box testing is a testing method that treats the program as a black box and only tests the input and output of the program . In CMS development, black box testing thinking can help you ensure the correctness of your program, especially in the user interface. For optimal testing, you need to test different data inputs and compare them to expected outputs. If there are any differences, further debugging and modification of the code will be required.

5. Using PHP’s Error Handling Function

PHP’s error handling function allows developers to handle various types of errors, including fatal errors, errors, notifications, and warnings. When developing a CMS, we should prioritize handling fatal errors to ensure system stability. In addition, we should also enable PHP's error logging function, so that errors and warnings can be recorded, allowing in-depth debugging of the problem.

Summary

This article provides a more in-depth look at some of the best debugging techniques in CMS programming for PHP development. Using these tips, you'll not only debug your code better, but you'll also improve code quality and maintainability. If you are a PHP developer, be sure to master these debugging skills, which will greatly improve your coding efficiency and the quality of your work.
