laravel best practices rules
When reviewing or writing code, apply these guidelines:
- Use Eloquent ORM instead of raw SQL queries when possible.
- Implement Repository pattern for data access layer.
- Use Laravel's built-in authentication and authorization features.
- Utilize Laravel's caching mechanisms for improved performance.
- Implement job queues for long-running tasks.
- Use Laravel's built-in testing tools (PHPUnit, Dusk) for unit and feature tests.
- Implement API versioning for public APIs.
- Use Laravel's localization features for multi-language support.
- Implement proper CSRF protection and security measures.
- Use Laravel Mix for asset compilation.
- Implement proper database indexing for improved query performance.
- Use Laravel's built-in pagination features.
- Implement proper error logging and monitoring.
laravel package coding standards
When reviewing or writing code, apply these guidelines:
- File names: Use kebab-case (e.g., my-class-file.php)
- Class and Enum names: Use PascalCase (e.g., MyClass)
- Method names: Use camelCase (e.g., myMethod)
- Variable and Properties names: Use snake_case (e.g., my_variable)
- Constants and Enum Cases names: Use SCREAMING_SNAKE_CASE (e.g., MY_CONSTANT)
laravel package development guidelines
When reviewing or writing code, apply these guidelines:
- Use PHP 8.3+ features where appropriate
- Follow Laravel conventions and best practices
- Utilize the spatie/laravel-package-tools boilerplate as a starting point
- Implement a default Pint configuration for code styling
- Prefer using helpers over facades when possible
- Focus on creating code that provides excellent developer experience (DX), better autocompletion, type safety, and comprehensive docblocks
laravel package structure
When reviewing or writing code, apply these guidelines:
- Outline the directory structure for the package
- Describe the purpose of each main directory and key files
- Explain how the package will be integrated

Iron Laws
- ALWAYS use parameterized queries or Eloquent ORM — raw SQL with string interpolation is the primary SQL injection vector in PHP; Eloquent's query builder parameterizes all values automatically.
- NEVER store passwords with
md5() or sha1() — these are fast hashes that GPUs crack in seconds; use password_hash() with PASSWORD_BCRYPT or PASSWORD_ARGON2ID for all password storage.
- ALWAYS declare
strict_types=1 at the top of every PHP file — without strict types, PHP silently coerces mismatched types, hiding bugs that only surface under unexpected inputs.
- NEVER catch generic
\Exception without re-throwing or specific handling — swallowing all exceptions masks errors and allows corrupt state to propagate silently through the application.
- ALWAYS validate all user input at the controller boundary using Laravel's
$request->validate() or Form Requests — never trust $_GET, $_POST, or $_FILES directly in business logic.
Anti-Patterns
| Anti-Pattern |
Why It Fails |
Correct Approach |
| Raw SQL with string interpolation |
Primary SQL injection vector; user input executed as SQL |
Use Eloquent ORM or PDO parameterized queries for all database access |
| Passwords stored with md5() or sha1() |
Fast hashes cracked in seconds by GPU rainbow tables |
Use password_hash() with PASSWORD_BCRYPT or PASSWORD_ARGON2ID |
Missing strict_types=1 |
PHP silently coerces types; bugs hide until unexpected inputs arrive |
Declare <?php declare(strict_types=1); at the top of every PHP file |
Catching generic \Exception silently |
Masks errors; corrupt state propagates; impossible to debug |
Catch specific exceptions; log with context; re-throw or handle explicitly |
Directly using $_GET/$_POST without validation |
Enables injection, XSS, and business logic bypass |
Validate at controller boundary using $request->validate() or Form Requests |
