phpstorm在centos上的代码检查功能

Installing Java Development Kit (JDK)
PhpStorm requires a Java runtime environment (JRE) to operate. On CentOS, install OpenJDK 11 or higher using the package manager:

sudo yum install openjdk-11-jdk

Verify the installation with:

java -version

This ensures PhpStorm has the necessary Java environment to run.

Downloading and Installing PhpStorm
Download the Linux version of PhpStorm from JetBrains’ official website. Extract the archive to a directory (e.g., /opt/phpstorm) using:

sudo tar -xvzf PhpStorm-*.tar.gz -C /opt/phpstorm

Optionally, add the PhpStorm binary directory to your system’s PATH by editing ~/.bashrc (or ~/.profile) and appending:

export PATH=$PATH:/opt/phpstorm/bin

Reload the configuration with source ~/.bashrc. Start PhpStorm by running /opt/phpstorm/bin/phpstorm.sh.

Configuring PHP Interpreter
To enable PhpStorm to analyze PHP code, set the PHP interpreter:

1. Go to File > Settings > Project: [Your Project Name] > PHP Interpreter.
2. Click the gear icon and select Add.
3. Choose the PHP executable (e.g., /usr/bin/php) and click OK.
   This allows PhpStorm to validate PHP syntax and run inspections against your project’s PHP version.

Setting Up Code Inspection Tools
PhpStorm supports multiple tools for enforcing code standards and static analysis. A common choice is PHP Code Sniffer (phpcs):

1. Install phpcs globally using Composer:

   composer global require "squizlabs/php_codesniffer=*"
   

2. In PhpStorm, navigate to File > Settings > Languages & Frameworks > PHP > Code Sniffer.
3. Click the Configuration button and select the phpcs executable path (e.g., ~/.composer/vendor/bin/phpcs).
4. Click Validate to confirm the path is correct.
5. Enable phpcs in inspections: go to Editor > Inspections > PHP, check PHP Code Sniffer Validation, and select a ruleset (e.g., PSR2).

Running Manual Code Inspection
To analyze your entire project or selected files:

1. Right-click the project root or a specific file/folder in the Project View.
2. Select Analyze > Inspect Code.
3. In the Inspection Profile dialog, choose a predefined profile (e.g., “PHP”) or create a custom one.
4. Click OK to start the inspection. Results will appear in the Inspection Results panel, showing issues (e.g., syntax errors, style violations) with suggested fixes.

Enabling Real-Time Code Checking
PhpStorm provides real-time feedback as you type. To ensure this is active:

1. Go to Editor > Inspections.
2. Verify that inspections are enabled (the toggle is on).
3. Adjust severity levels (e.g., mark “Undefined variable” as an error) to prioritize issues.
   Real-time checks highlight problems immediately, reducing the need for manual runs.

Optional: Configuring Other Tools
For deeper static analysis, integrate tools like PHPStan or Psalm:

• PHPStan: Install via Composer (composer global require phpstan/phpstan), then configure the executable path in Settings > Languages & Frameworks > PHP > Code Sniffer.
• Psalm: Install via Composer (composer global require phpstan/psalm), then follow similar steps to add it to PhpStorm.
  These tools provide advanced checks (e.g., type safety, unused code) to further improve code quality.
