laravel package coding standards

Laravel包编码规范

When reviewing or writing code, apply these guidelines:
  • File names: Use kebab-case (e.g., my-class-file.php)

laravel package development guidelines

Laravel包开发指南

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
在审查或编写代码时,遵循以下规范:
  • 合适的场景下使用PHP 8.3+的新特性
  • 遵循Laravel的约定和最佳实践
  • 以spatie/laravel-package-tools模板作为开发起点
  • 配置默认的Pint规则统一代码风格
  • 尽可能使用辅助函数而非Facade
  • 重点关注代码的开发者体验(DX),提供更好的自动补全、类型安全和完善的注释

laravel package structure

Laravel包结构规范

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
</instructions> <examples> Example usage: ``` User: "Review this code for php best practices" Agent: [Analyzes code against consolidated guidelines and provides specific feedback] ``` </examples>
在审查或编写代码时,遵循以下规范:
  • 梳理包的目录结构
  • 说明每个核心目录和关键文件的作用
  • 解释包的集成方式
</instructions> <examples> 使用示例: ``` 用户:"请基于PHP最佳实践审查这段代码" Agent:[基于整合的规范分析代码并给出具体反馈] ``` </examples>

Iron Laws

铁律

  1. 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.
  2. 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.
  3. 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.
  4. 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.
  5. 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.
  1. 必须使用参数化查询或者Eloquent ORM —— 带字符串插值的原生SQL是PHP中SQL注入的主要风险来源;Eloquent的查询构建器会自动为所有值做参数化处理。
  2. 严禁使用
    md5()
    sha1()
    存储密码 —— 这类哈希算法计算速度快,GPU可以在几秒内破解;所有密码存储都要使用
    password_hash()
    配合
    PASSWORD_BCRYPT
    或者
    PASSWORD_ARGON2ID
    实现。
  3. 必须在每个PHP文件顶部声明
    strict_types=1
    —— 没有开启严格类型时,PHP会静默处理不匹配的类型,导致只有遇到意外输入时才会暴露的隐藏bug。
  4. 严禁捕获通用
    \Exception
    后不重新抛出也不做特定处理 —— 吞掉所有异常会掩盖错误,导致损坏的状态在应用中静默传播。
  5. 必须在控制器层使用Laravel的
    $request->validate()
    或者表单请求校验所有用户输入 —— 业务逻辑中永远不要直接信任
    $_GET
    $_POST
    或者
    $_FILES
    的内容。

Anti-Patterns

反模式

Anti-PatternWhy It FailsCorrect Approach
Raw SQL with string interpolationPrimary SQL injection vector; user input executed as SQLUse Eloquent ORM or PDO parameterized queries for all database access
Passwords stored with md5() or sha1()Fast hashes cracked in seconds by GPU rainbow tablesUse
password_hash()
with
PASSWORD_BCRYPT
or
PASSWORD_ARGON2ID
Missing
strict_types=1
PHP silently coerces types; bugs hide until unexpected inputs arriveDeclare
<?php declare(strict_types=1);
at the top of every PHP file
Catching generic
\Exception
silently
Masks errors; corrupt state propagates; impossible to debugCatch specific exceptions; log with context; re-throw or handle explicitly
Directly using
$_GET
/
$_POST
without validation
Enables injection, XSS, and business logic bypassValidate at controller boundary using
$request->validate()
or Form Requests
反模式问题原因正确方案
带字符串插值的原生SQL主要的SQL注入风险来源;用户输入会作为SQL执行所有数据库操作都使用Eloquent ORM或者PDO参数化查询
使用md5()或sha1()存储密码这类快速哈希可以通过GPU彩虹表在几秒内破解使用
password_hash()
配合
PASSWORD_BCRYPT
或者
PASSWORD_ARGON2ID
存储密码
未声明
strict_types=1
PHP会静默做类型转换;bug会一直隐藏直到遇到意外输入在每个PHP文件顶部声明
<?php declare(strict_types=1);
静默捕获通用
\Exception
掩盖错误;导致状态损坏传播;无法排查问题捕获特定异常;记录上下文日志;显式处理或者重新抛出异常
未校验直接使用
$_GET
/
$_POST
存在注入、XSS和业务逻辑绕过风险在控制器层使用
$request->validate()
或者表单请求做校验

Memory Protocol (MANDATORY)

内存协议(强制要求)

Before starting:
bash
cat .claude/context/memory/learnings.md
After completing: Record any new patterns or exceptions discovered.
ASSUME INTERRUPTION: Your context may reset. If it's not in memory, it didn't happen.
开始前执行:
bash
cat .claude/context/memory/learnings.md
**完成后:**记录所有发现的新模式或者例外情况。
假设存在中断风险:你的上下文可能会重置。如果内容没有保存在内存中,就等于没有发生过。
