PHP development: Code debugging using PHPStorm

In PHP development, debugging is a very important task. It can help us quickly locate and solve problems and improve development efficiency. In this article, we will explore how to use PHPStorm for code debugging, let’s take a look.

First, we need to install PHPStorm and the Xdebug extension. In PHPStorm, we can set up Xdebug by entering "Settings" -> "Languages & Frameworks" -> "PHP" -> "Debug". We need to manually enable Xdebug and configure port number, remote IP address and other information. After configuring, we need to click the "Validate" button to confirm whether the configuration is correct.

Next, we need to open our PHP project and create a new run configuration in PHPStorm. We can open the run configuration interface through "Run" -> "Edit Configurations".

In the run configuration interface, we need to select PHP Remote Debug. Here we need to fill in the IP and port number of the remote server, and set the root directory of the server. In addition, we can also choose to enable the script feature to pause script execution when certain conditions are encountered.

After configuring the running configuration, we need to add breakpoints in the code to debug the code. We can add breakpoints by clicking on an empty space to the left of a line of code. When the program runs to the code line where a breakpoint has been added, the program will pause execution, and we will be able to view information such as current variables and function stacks.

In addition to adding breakpoints in the code, we can also further optimize the debugging experience by setting conditional breakpoints, disabling breakpoints, etc. In addition, we can also use PHPStorm's many debugging tools, such as "Watches", "Variables", etc., to view variables, functions and other information more conveniently.

After debugging is completed, we can remove breakpoints by manually removing them or selecting "Run" -> "Remove All Breakpoints". In addition, we can also add log information to the code to assist debugging.

In summary, using PHPStorm for code debugging can help us quickly locate and solve problems, and improve code quality and development efficiency. Through the above introduction, I believe that readers can already skillfully use PHPStorm for debugging.
