How to use tools to automatically check whether PHP code complies with the latest code specifications?

Introduction:
In the software development process, we often need to follow certain code specifications to ensure the readability, maintainability and scalability of the code. However, manually checking code specifications is a tedious and error-prone task. In order to improve efficiency and reduce errors, we can use some tools to automatically check code specifications. In this article, I will introduce how to use some popular tools to automatically check whether PHP code complies with the latest coding standards.

1. PHP Code Sniffer (PHP code sniffer)
PHP Code Sniffer is a popular PHP code specification checking tool. It can help us automatically check whether the PHP code complies with pre-defined code specifications. The following are the steps to use PHP Code Sniffer:

1. Install PHP Code Sniffer
   You can install PHP Code Sniffer through Composer. Open the terminal and execute the following command:

   composer global require "squizlabs/php_codesniffer=*"

2. Configure code specification
   PHP Code Sniffer supports multiple code specifications, such as PSR-2, PSR-12, etc. You can create a .phpcs.xml file in your project and specify the required code specifications:

   <?xml version="1.0"?>
   <ruleset name="My Project">
    <rule ref="PSR2"/>
   </ruleset>

3. Run code inspection
   In the terminal, enter your project directory, and execute the following command to run code inspection:

   phpcs --standard=./.phpcs.xml ./src

   where, --standard=./.phpcs.xml means using .phpcs.xml## Check the code specifications defined in #, ./src indicates the code directory to be checked.

2. PHP-CS-Fixer (PHP code repair tool)

PHP-CS-Fixer is another popular PHP code specification checking and automatic repair tool. Unlike PHP Code Sniffer, PHP-CS-Fixer can not only check code specifications, but also automatically fix code that does not meet the specifications. The following are the steps to use PHP-CS-Fixer:

1. Install PHP-CS-Fixer

   You can install PHP-CS-Fixer through Composer. Open the terminal and execute the following command:
   

   composer global require friendsofphp/php-cs-fixer

2. Configure code specification

   PHP-CS-Fixer also supports multiple code specifications, and you can create one in the project
   .php_cs file and specify the required code specifications:

   <?php
   return PhpCsFixerConfig::create()
    ->setRules([
        '@PSR2' => true,
    ])
    ->setRiskyAllowed(true);

3. Run Code Check and Fix

   In the terminal, go into your project directory and execute the following command to run the code Check and repair:
   

   php-cs-fixer fix ./src

   Among them, the

   fix command will automatically repair code that does not comply with the specification.

Conclusion:

By using PHP Code Sniffer and PHP-CS-Fixer, we can easily automatically check and fix whether PHP code complies with the latest code specifications. These tools can not only improve development efficiency, but also ensure code quality and consistency. Therefore, in daily development, we should develop the habit of using these tools to ensure the code quality of the project.
