A framework gives you standard solutions to typical problems, e.g. for an online shop that can cover the functionality for a customer login (including session handling), a shopping cart, placing orders...
框架为您提供了典型问题的标准解决方案，例如，可以涵盖客户登录（包括会话处理）、购物车、下订单等功能的在线商店。
The big advantage of using a framework is that
使用框架的最大优势在于
- You don't need to reinvent the wheel, the code is already there
- The code (usually) works, it is already tested
- Specifically for user authentication, you will most probably have fewer security leaks as if you invented something from scratch yourself
- 你不需要重新发明轮子，代码已经在那里了
- 代码（通常）有效，它已经过测试
- 特别是对于用户身份验证，您很可能会减少安全漏洞，就像您自己从头开始发明一样
The big disadvantage is that
最大的缺点是
- If you want to extend the functionality, you have to understand OPC (other peoples code)
- If the framework contains a security hole and an exploit is available, your site is immediately vulnerable, but you may not have the knowledge to fix it yourself. So you need to keep a constant lookout on security bulletins, updates, fixes etc.
- 如果你想扩展功能，你必须了解OPC（其他人的代码）
- 如果框架包含安全漏洞并且存在漏洞利用，则您的站点立即易受攻击，但您可能不具备自行修复它的知识。因此，您需要不断关注安全公告、更新、修复等。

A framework is a library. You have an investment of time to learn how to use a library, but once you know how it works, you should get back your investment many times.
框架是一个库。您需要投入时间来学习如何使用库，但是一旦您知道它是如何工作的，您就应该多次收回您的投资。
A PHP web framework applies this principle to all the common things you do when you produce a (usually database driven) website with PHP.
PHP Web 框架将此原则应用于您使用 PHP 生成（通常是数据库驱动的）网站时所做的所有常见事情。
