PSR-12

Overview In Laravel development, clean code often conflicts with standard compliance. Developers frequently use grouped `use` statements to avoid repeating namespace prefixes for controllers. While this appears elegant and reduces line counts in `routes/web.php`, it often conflicts with PSR-12 coding standards. Standardizing these imports ensures your codebase remains compatible with automated tooling and maintains a professional, predictable structure across large teams. This tutorial demonstrates how to enforce single-line imports using Laravel Pint. Prerequisites To follow this guide, you should have a Laravel application installed (version 9.x or higher includes Pint by default). You need a basic understanding of PHP namespaces and how the `use` keyword functions within the framework's routing files. Access to a terminal is required to execute the formatting commands. Key Libraries & Tools * **Laravel Pint**: A zero-config PHP code style fixer built on top of PHP-CS-Fixer, designed specifically for the Laravel ecosystem. * **PSR-12**: The PHP Standard Recommendation that dictates modern coding styles, including the preference for individual import statements. Code Walkthrough The Violation Typically, developers might group controllers within a single block to save space. While functional, this is the pattern we want to change: ```php use App\Http\Controllers\{ DashboardController, ProfileController, SettingsController }; ``` Configuration Create a `pint.json` file in your project's root directory. This configuration tells the fixer to strictly enforce one import per statement. ```json { "rules": { "single_import_per_statement": true } } ``` Execution Run the following command in your terminal. Pint will scan your files and automatically restructure your routes. ```bash ./vendor/bin/pint ``` Syntax Notes The `single_import_per_statement` rule specifically targets the block syntax. Once executed, Pint transforms the grouped block into a series of individual `use` statements. This follows the standard that each class should have its own dedicated line, making git diffs easier to read when a single controller is added or removed. Practical Examples After running the tool, your route file will look like this: ```php use App\Http\Controllers\DashboardController; use App\Http\Controllers\ProfileController; use App\Http\Controllers\SettingsController; ``` This format is the industry standard. It prevents merge conflicts in version control and ensures that every class dependency is explicitly visible at a glance. Tips & Gotchas Always run Pint before committing code. If you use an IDE like PHPStorm or VS Code, you can set up a "format on save" hook to trigger Pint automatically. Remember that while grouped statements are valid PHP syntax, sticking to the single-statement rule makes your project align with the wider PHP community's expectations.
