phpstorm在centos中的代码检查

Installing Required Tools on CentOS
Before configuring code inspection in PhpStorm, ensure your CentOS system has the necessary dependencies installed. Start by installing PHP and essential extensions using YUM:

sudo yum install php php-cli php-fpm php-mysql php-xml php-json

Verify PHP installation with php -v. For Java support (required by PhpStorm), install OpenJDK 11 or higher:

sudo yum install openjdk-11-jdk
java -version  # Confirm installation

Configuring PhpStorm Basics
After downloading PhpStorm from JetBrains’ website and extracting it to a directory (e.g., /opt/phpstorm), configure the PHP interpreter:

1. Open PhpStorm → File → Settings → Languages & Frameworks → PHP.
2. Click the “…” button next to “CLI Interpreter” and select the PHP binary path (found via which php).
   This ensures PhpStorm recognizes your PHP environment for inspections.

Setting Up Code Inspection Tools
PhpStorm supports multiple tools for enforcing code standards and static analysis. Below are key configurations for popular tools:

PHP Code Sniffer (phpcs)

PHP Code Sniffer checks code against coding standards like PSR2. Install it globally via Composer:

composer global require "squizlabs/php_codesniffer=*"

Configure PhpStorm to use phpcs:

1. Go to File → Settings → Languages & Frameworks → PHP → Code Sniffer.
2. Click “Configuration” and select the phpcs executable (typically at ~/.composer/vendor/bin/phpcs).
3. Click Validate to confirm the path is correct.
4. Enable inspections: Expand Editor → Inspections → PHP, check “PHP Code Sniffer Validation”, and select a ruleset (e.g., PSR2).

PHP Mess Detector (phpmd)

PHPMD detects unused variables, suboptimal code, and other complexity issues. Install it globally:

composer global require "phpmd/phpmd=*"

Configure PhpStorm:

1. Navigate to File → Settings → Languages & Frameworks → PHP → Quality Tools → PHP Mess Detector.
2. Click “Configuration” and select the phpmd executable (typically at ~/.composer/vendor/bin/phpmd).
3. Click Validate to ensure the path is correct.

PHPStan/Psalm (Static Analysis)

For deeper static analysis (e.g., type safety, undefined classes), install PHPStan or Psalm:

composer global require "phpstan/phpstan"  # For PHPStan
composer global require "psalm/psalm"      # For Psalm

Configure in PhpStorm (Languages & Frameworks → PHP → Code Sniffer) by selecting the tool’s executable and validating the path.

Enabling Real-Time and Manual Inspections
PhpStorm runs inspections by default as you type, highlighting issues with red/yellow underlines. To run manual inspections:

1. Right-click your project root in the Project view.
2. Select Analyze → Inspect Code.
3. Choose a scope (entire project, current file, or custom directory) and click OK.
   Results appear in the Inspection Results panel, where you can view details and fix issues.

Adjusting Inspection Rules
Customize inspection severity (errors, warnings, hints) via Settings → Editor → Inspections → PHP. Expand categories (e.g., “PHP Syntax”, “Code Smell”) to enable/disable specific rules or change their severity level.

By following these steps, you can set up robust code inspection in PhpStorm on CentOS, ensuring your PHP code adheres to standards and is free from common issues.
