Master the correct debugging skills to make PHP language development easy and stress-free

As a developer, debugging is a crucial part of the development process. It can help us find problems in the code and solve them. As a commonly used language, PHP often requires debugging during the development process. This article will introduce some PHP debugging techniques to help developers easily cope with the debugging process.

1. Use var_dump() and print_r() to display variable information

As one of the most commonly used methods during debugging, you can easily output variables using var_dump() and print_r() information to check the type and value of the variable. var_dump() prints the variable name, type and value, while print_r() only prints the value.

2. Use error_reporting() and ini_set() to print out error information

PHP provides some functions to help us print out error information. During debugging, error_reporting() can be used in the script. Enable error reporting, where parameter 1 means that all errors will be reported.

At the same time, use ini_set() to modify the settings in the PHP configuration file at runtime. The combination of the two can be used very well to track error messages that appear in the code.

3. Use xdebug for debugging

xdebug is a PHP debugger extension that can make the debugging process more efficient. When using xdebug, we need to create a new xdebug configuration file and specify the type, port and IP address of the debugger connection. Then add a breakpoint in the code, start xdebug, and a prompt will appear when accessing the web page. After clicking OK, you can enter the breakpoint and start debugging.

4. Use PHPStorm for debugging

PHPStorm is a very popular PHP development tool with very powerful debugging functions. When using PHPStorm for debugging, we need to create a remote debugging configuration in PHPStorm, select PHP Web Application, and set the server address and port.

Then, add breakpoints in the code, start a PHP remote debugging session, and when the page access event is triggered, PHPStorm will automatically pause the program, allowing you to check variables, step execution, etc.

To sum up, mastering correct debugging skills can greatly improve the efficiency and accuracy of PHP development. By using var_dump() and print_r(), error_reporting() and ini_set(), xdebug and PHPStorm, we can debug code more efficiently and contribute to the success of the project.
