PHP中的數據庫操作有MySQL,MySQLi,PDO三種,可以用適配器模式統一成一致,使不同的數據庫操作,統一成一樣的API。類似的場景還有cache適配器,可以將memcache,redis,file,apc等不同的緩存函數,統一成一致。? 首先定義一個接口(有幾個方法,以及相應的參數)。然后,有幾種不同的情況,就寫幾個類實現該接口。將完成相似功能的函數,統一成一致的方法。 ![](https://img.kancloud.cn/2e/40/2e4097f54ecb8573ba80073573d30db4_1573x585.png) **示例代碼:** ![](https://img.kancloud.cn/37/40/3740444a9946057025a21a6ea594df2d_663x275.png) 特定數據庫mysql ![](https://img.kancloud.cn/b4/8d/b48d588bfdca4162d8a60c703bf017ef_662x584.png)
