PHPCS Git Check

PHPCS Git Check is a smart VS Code extension that runs PHPCS only on Git-changed lines (staged and unstaged), avoiding unnecessary warnings and noise. Ideal for teams working with large or legacy PHP codebases.

📦 Features

  • Runs PHPCS only on changed lines from Git diff (staged + unstaged)
  • Supports on save, on open, on focus, and on startup
  • Debounced checks to avoid rapid duplicate runs
  • Custom diagnostics colors (Warnings = yellow, Info = blue)
  • Only checks .php files inside a Git repo

🚀 Commands

Command Palette → PHPCS Git Check: Run PHPCS on Changed Lines

⚙️ Settings

Setting Type Default Description
phpcsGitCheck.checkOnStartup boolean true Automatically run on all changed files on startup
phpcsGitCheck.checkOnSave boolean true Automatically run on save for PHP files
phpcsGitCheck.checkOnOpen boolean true Run PHPCS when a file is opened
phpcsGitCheck.checkOnFocus boolean true Run PHPCS when the editor gains focus

🧪 Example

If you change lines 10–12 in a PHP file, the extension will:

  • Use git diff and git diff --cached to detect modified lines
  • Run PHPCS on the file
  • Show only errors/warnings that apply to those lines

📁 Files Used

  • phpcs.xml.dist or phpcs.xml (optional PHPCS config)
  • Git commands:
    • git diff -U0 <file> (unstaged changes)
    • git diff --cached -U0 <file> (staged changes)

🧬 Diagnostics Behavior

📌 Limitations

  • Only works inside initialized Git repositories
  • Only supports .php files
  • Only checks Git-diffed lines — not the entire file

✅ Summary

PHPCS Git Check is the perfect linter for working on modern or legacy codebases, focusing only on what you’ve changed.


PHPCS Git Check gives you focused, efficient linting:

✅ Prevents noise from legacy code ✅ Checks what you actually changed ✅ Integrates cleanly into your Git workflow


🧪 Test Case Suggestions

1. Staged + Unstaged Changes

<?php
// Line 5: staged
echo  "Hello, World!" ;

// Line 15: unstaged
if($foo==true){
echo 'bar';
}

Run:

git add yourfile.php
# Modify line 15 after adding
# Save in VS Code

→ The extension should report both line 5 and 15 issues.


Happy Coding! 🎉
