FAQ
After the download, you have to make one include require_once('vendor/autoload.php');. After that you have to import the classes with use statements.
Example:
Example:
If you use only one package a project is not needed. But if you use more then one package, without a project it is not possible to import the classes with use statements.
In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.

Some PHP packages are not free to download and because of that hosted in private repositories.
In this case some credentials are needed to access such packages.
Please use the auth.json textarea to insert credentials, if a package is coming from a private repository.

- Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
- To use Composer is sometimes complicated. Especially for beginners.
- Composer needs much resources. Sometimes they are not available on a simple webspace.
- If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
- Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.

Informations about the package think-orm-async
ThinkOrmAsync - think-orm 异步批量查询扩展
功能特性
- ✅ 透明的异步查询 API（与同步代码完全一致）
- ✅ 支持 ORM 查询和原生 SQL 查询
- ✅ 自动从 ThinkPHP 配置读取数据库配置
- ✅ 自动连接重试（仅限连接错误）
- ✅ 延迟加载结果占位符
- ✅ 零侵入集成（trait + 单例）
- ✅ 非 Swoole 环境可用（纯 PHP mysqli）
安装
快速开始
1. 在模型中引入 trait
2. 使用异步查询
基本使用
ORM 查询
原生 SQL 查询
混合使用 ORM 和原生查询
配置
自动配置（推荐）
在 ThinkPHP 项目中，AsyncContext::start() 会自动从 config('database.connections.mysql') 读取配置：
手动配置
在非 ThinkPHP 项目中，需要手动传递配置：
设置超时
重试机制
仅重试连接错误，不重试 SQL 逻辑错误。
可重试错误
- 2002: Connection refused
- 2003: Can't connect to MySQL server
- 2006: MySQL server has gone away
- 2013: Lost connection to MySQL server during query
不重试错误
- SQL 语法错误 (1064)
- 表不存在 (1146)
- 字段不存在 (1054)
- 权限错误
- 其他 SQL 逻辑错误
重试策略
- 最多重连一次（总共最多执行 2 次）
- 固定延迟 1 秒后重连
- 重连失败后抛出异常
错误处理
处理查询失败
处理部分失败
高级用法
数组访问和遍历
转换为数组和 JSON
获取模型对象
辅助方法
注意事项
- ThinkPHP 环境：在 ThinkPHP 项目中，会自动从
config('database.connections.mysql')读取配置 - mysqlnd 驱动：需要使用 mysqlnd 驱动（PHP 5.3+ 默认）
- 不要在循环中使用：避免在循环中嵌套
AsyncContext::start()/AsyncContext::end() - 错误处理：查询失败时会抛出异常，需要自行处理
- 表前缀：确保模型类正确设置了
$name和$prefix属性
性能提升
在多个独立查询的场景下，异步查询可以显著减少网络往返延迟：
| 查询数 | 同步查询 | 异步查询 | 提升 |
|---|---|---|---|
| 3 | 300ms | 150ms | 50% |
| 5 | 500ms | 200ms | 60% |
| 10 | 1000ms | 350ms | 65% |
假设：每个查询平均耗时 100ms，网络往返 50ms
测试
测试使用 Pest 框架，使用 Mock 对象，无需真实数据库连接。
