How to add the latest PHP code specification requirements for personal development style?

Introduction:
PHP is a widely used server-side scripting language. It is easy to learn and use, so it is widely used in the development process. However, due to the different coding habits of each developer, inconsistent coding styles may result. In order to improve code quality and readability, it is crucial to introduce the latest PHP code specification requirements. This article will introduce how to add the latest PHP code specification requirements for your personal development style, with code examples.

Step one: Understand the latest PHP code specification requirements
Before we start, we need to understand the latest PHP code specification requirements. At present, the PHP community widely adopts the PSR series of code specifications, the most commonly used of which are PSR-1 and PSR-2. The PSR-1 specification focuses on basic coding conventions, while the PSR-2 specification focuses more on coding style and layout.

Step 2: Configure the development environment
In order to be able to check and automatically repair code specification issues, we need to configure the corresponding development environment. It is recommended to use PHP coding standard checking tools, such as PHP_CodeSniffer and PHP-CS-Fixer. These tools can be installed and configured through Composer.

The following is the sample code for installing PHP_CodeSniffer and PHP-CS-Fixer through Composer:

composer require squizlabs/php_codesniffer
composer require friendsofphp/php-cs-fixer

Step 3: Create a personal code specification file
Create one in the project root directory.phpcs.xml file and add the following content:

<?xml version="1.0"?>
<ruleset name="Custom Coding Standard">
    <arg name="tab-width" value="4"/>
    <arg name="extensions" value="php"/>
    <file>./</file>
    <rule ref="PSR1"/>
    <rule ref="PSR2"/>
</ruleset>

This file specifies the encoding convention to use and the folder to check. In this example, we used the PSR1 and PSR2 specifications and specified all PHP files in the project root directory to be checked.

Step 4: Run the code specification check
Enter the following command in the command line to run the code specification check:

./vendor/bin/phpcs

If it encounters a specification problem, it will give the corresponding warning and error messages. Depending on the prompts, we can modify the code and rerun the checks until all specification issues are resolved.

Step 5: Automatically fix code specification issues
Sometimes, fixing all specification issues manually can be tedious. Fortunately, the PHP-CS-Fixer tool can automatically fix some specification issues. Enter the following command on the command line to run the automatic repair operation:

./vendor/bin/php-cs-fixer fix

It will automatically perform repair operations in the code. If a specification issue is found, it will be automatically repaired.

Summary:
By following the latest PHP code specification requirements, we can improve code quality and readability, thereby better organizing and maintaining our code. The above are the steps to add the latest PHP code specification requirements for your personal development style, with relevant code examples attached.
