How to use tools to normalize PHP code to meet the latest coding standards?

Overview:
In the team development process, code specifications are a very important part. Following unified code specifications can enhance the readability and maintainability of code and improve team collaboration efficiency. In PHP development, there are many tools that can help us automatically check and fix code specification issues. This article will introduce several commonly used PHP code specification tools and provide corresponding code examples.

1. PHP CodeSniffer
PHP CodeSniffer is a widely used PHP code specification checking tool. It uses a set of rules (such as PSR-2 or a custom rule set) to detect code specification issues and give timely warnings or error prompts. The following is an example of using PHP CodeSniffer for code specification checking:

1. First, we need to install CodeSniffer. Open the terminal and execute the following command:

composer global require "squizlabs/php_codesniffer=*"

2. Then, enter our PHP project directory and execute the following command:

phpcs --standard=PSR2 ./src

Among them, --standard=PSR2 means using the PSR-2 specification Perform code specification check. ./src means checking the src folder in the current directory.

2. PHP-CS-Fixer
PHP-CS-Fixer is another commonly used PHP code specification repair tool. It can automatically fix many code specification issues and help us maintain consistency in coding style. The following is an example of using PHP-CS-Fixer to fix code specifications:

1. First, we need to install PHP-CS-Fixer. Open the terminal and execute the following command:

composer global require friendsofphp/php-cs-fixer

2. Next, enter our PHP project directory and execute the following command:

php-cs-fixer fix ./src --rules=@PSR2

Among them, fix means to fix the code specification problem, ./src Indicates repairing the src folder in the current directory. --rules=@PSR2 indicates using the PSR-2 specification for repair.

3. IDE integrated tools
Many PHP integrated development environments (such as PHPStorm and Visual Studio Code) support integrated code specification tools, which can automatically detect and repair code specification issues during the coding process. The following is an example of using PHPStorm to integrate CodeSniffer:

1. Open PHPStorm and enter the Settings/Preferences interface.
2. Select the Editor -> Inspections option.
3. Search for "Code Sniffer" in the search box on the right.
4. Check Code Sniffer and select the corresponding rule set (such as PSR-2).
5. Save the settings and be reminded of code specification issues through real-time detection and prompts during the coding process.

Conclusion:
By using tools to standardize PHP code, we can follow the latest code specifications and improve code quality and maintainability. In team collaboration, maintaining a consistent coding style is also very important. I hope the PHP code specification tools and examples introduced in this article will be helpful to you and make your PHP code more standardized and readable.
