这篇文章主要为大家详细介绍了PHP设计模式下简单投诉页面实例，感兴趣的小伙伴们可以参考一下，本文实例介绍了PHP简单投诉页面的实现代码，分享给大家供大家参考，具体内容如下

php代码：

1. <?php
2. /*
3. * 设计模式练习
4. * 1.数据库连接类（单例模式）
5. * 2.调用接口实现留言本功能（工厂模式）
6. * 3.实现分级举报处理功能（责任链模式）
7. * 4.发送不同组合的举报信息（桥接模式）
8. * 5.发送不同格式的举报信息（适配器模式）
9. * 6.在投诉内容后自动追加时间（装饰器模式）
10. * 7.根据会员登录信息变换显示风格（观察者模式）
11. * 8.根据发帖长度加经验值（策略模式）
