值得分享的php+ajax实时聊天室

非常经典的一款php+ajax实时聊天室,其中使用PHP新濠天地保存聊天记录,按天划分,PHP实现聊天的新濠天地只有一个新濠天地,整合了PHP与AJAX技术,也就是说只要运行这一个新濠天地就可以启动PHP的聊天室了,关于app上面也是非常的简单,但是实现了聊天室一般的新濠天地,聊天时的昵称,更改昵称的颜色,聊天字号大小,字体,加粗,窗体的变大变小等等,如果你想搞个聊天室来玩玩,这个源码完全可以满足普通的需求。

具体的效果看如下图:

关键app:


<?php
header('content-type:text/html;charset=utf-8');
//新濠天地在线用户
$disonline = 1;
//新登陆时新濠天地最近app的条数(默认为30条)
$leastnum = 30;
//默认的房间名(默认是每天换一个新濠天地),如果去掉d,则是每月换一个新濠天地
$room = date("Y-m-d");
//房间保存路径,必须仿quot;/"结尾,可以丿quot;../",等
$roomdir = "rooms/";
//编码方式
$charset = "utf-8";
//客户端最大新濠天地app条数(建议不要太大)
$maxdisplay = 300;
//语言包
$lang = array(
//聊天室描述
"description"=>"聊天室.",
//聊天室标题
"title"=>"Welcome...!",
//第一个到聊天室的欢迎
"firstone"=>"<span style='font-size:16px;color:blue;'>Welcome...!</span>",
//当信息有禁止app时新濠天地
"ban" => array('法轮功', '共产党', '李洪志', 'fuck', '叼', '你妈的', '他妈的'),
//关键字
"keywords"=>"Welcome...!",
//发言提示
"hereyourwords" => "在这里发言!"
);
