PHP實例：ThinkPHP無限級分類原理實現留言與回復功能實例
作者：VEPHP 時間 2018-03-13
《PHP實例：ThinkPHP無限級分類原理實現留言與回復功能實例》要點：
本文介紹了PHP實例：ThinkPHP無限級分類原理實現留言與回復功能實例，希望對您有用。如果有疑問，可以聯系我們。
PHP教程本文所述留言板程序使用了無限級分類的原理,可以實現無限級留言與回復.留言列表gclist保留了留言層次空格,使留言--回復層次分明.分享給大家供大家參考.具體分析如下：
PHP教程功能上,本程序可以實現無限級留言與回復,即對留言回復,對回復的留言回復.當然你也可以作有限制的控制,使其只對留言回復,關鍵是在模板代碼中去掉回復的留言中的“回復該留言”即可.歡迎去拍磚!
PHP教程程序效果如下圖所示：
