Seagull是个纯OOP(面向对象程序设计)框架,可用于创建web,command line(命令行)和GUI的应用程序.它采用了BSD授权,让PHP开发者可以更容易地整合并管理代码源,更快速地建立复杂的应用程序。目前Seagull设计中已集成了许多比较受欢迎的PHP应用程序,例如:各式各样的模板引擎,测试工具,管理代码库工具等.如果您是个初学者,您可以将Seagull提供的许多样本应用程序自定义或扩展成适合您所需的.如果您是中高级开发者,您可以充分利用seagull中的best practices(最优方案),标准和模块的代码核心在有规定的时间内建立您的应用程序.

Seagul是面向对象程序设计的强调模块性的应用程序.框架的组成:

• 基本框架:框架本身由一组基本的类组成,这些类的组织依照MVC设计模式,主要处理权限,验证,SESSION,I/O和数据库抽象层.熟悉Struts和JSP配置的开发者会认可这种方法.
• 模块:每个功能性的推广范围以模块的形式出现,你的业务需求可能与框架中已存在的模块相匹配.如果有哪些模块不存在,请要求我们,我们的开发团队会尽力完善.如果由你的开发者构建并贡献给seagull,这当然是更好的.
• 库:大多数特殊任务的功能性来源于库,通常都来源于PEAR,当需要升级/改进时,它可以独立地被更新.
• 实体/实体管理:应用程序中的每个对象(Member,Group,Property,Document,Article等)都被描述成一个实体,开发者拥有快速原型实体的工具,因此skeleton(主干)类可被自动地创建和更新.
• 下面是官网的解释：

Seagull is a mature OOP framework for building web, command line and GUI applications. Licensed under BSD, the project allows PHP developers to easily integrate and manage code resources, and build complex applications quickly.

Many popular PHP applications are already seamlessly integrated within the project, as are various templating engines, testing tools and managed library code. If you're a beginner, the framework provides a number of sample applications that can be customised and extended to suit your needs. If you're an intermediate or advanced developer, take advantage of Seagull's best practices , standards and modular codebase to build your applications in record time.

Once your development cycle is complete, use Seagull's features for deploying and maintaining your apps locally and remotely. Check out the friendly and active Seagull community and see if Seagull's a good fit for you.
