这篇文章主要介绍了值得分享的php+ajax实时聊天室,有图有真相,感兴趣的小伙伴们可以参考一下
非常经典的一款php+ajax实时聊天室,其中使用PHP文件保存聊天记录,按天划分,PHP实现聊天的功能只有一个文件,整合了PHP与AJAX技术,也就是说只要运行这一个文件就可以启动PHP的聊天室了,关于代码上面也是非常的简单,但是实现了聊天室一般的功能,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:
关键代码:
"聊天室.", //聊天室标题 "title"=>"Welcome...!", //第一个到聊天室的欢迎 "firstone"=>"Welcome...!", //当信息有禁止内容时显示 "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!" ); $touchs = 10; $title = $lang["title"]; $earlier = 10; $description = $lang["description"]; $origroom = $room; $least = ($_GET["dis"])?intval($_GET["dis"]):$leastnum; if ($_GET["room"]) $room = $_GET["room"]; $room = checkfilename($room); if (!$room) $room = $origroom; $filename = $roomdir.$room.".dat.php"; $datafile = $roomdir.$room.".php"; if (!is_dir($roomdir)) { @mkdir($roomdir, 0777) or exit('no this dir.'); } if(file_exists($filename)){ if ((int)filemtime($filename) + 1800 < time()) { unlink($filename); } } if (!file_exists($filename)) @file_put_contents($filename,''."\n".time()."|".$lang["firstone"]."\n"); if (!file_exists($datafile)) @file_put_contents($datafile,''."\n"); $action = $_GET["action"]; if (!function_exists("file_get_contents")) { function file_get_contents($path) { if (!file_exists($path)) return false; $fp=@fopen($path,"r"); $all=fread($fp,filesize($path)); fclose($fp); return $all; } } if (!function_exists("file_put_contents")) { function file_put_contents($path,$val) { $fp=@fopen($path,"w"); fputs($fp,$val); fclose($fp); return true; } } function checkfilename($file) { if (!$file) return ""; $file = trim($file); $a = substr($file,-1); $file = eregi_replace("^[.\\\/]*","",$file); $file = eregi_replace("[.\\\/]*$","",$file); $arr = array("../","./","/","\\","..\\",".\\"); $file = str_replace($arr,"",$file); return $file; } function get_ip() { global $_SERVER; if ($_SERVER) { if ( $_SERVER[HTTP_X_FORWARDED_FOR] ) $realip = $_SERVER["HTTP_X_FORWARDED_FOR"]; else if ( $_SERVER["HTTP_CLIENT_ip"] ) $realip = $_SERVER["HTTP_CLIENT_ip"]; else $realip = $_SERVER["REMOTE_ADDR"]; } else { if ( getenv( 'HTTP_X_FORWARDED_FOR' ) ) $realip = getenv( 'HTTP_X_FORWARDED_FOR' ); else if ( getenv( 'HTTP_CLIENT_ip' ) ) $realip = getenv( 'HTTP_CLIENT_ip' ); else $realip = getenv( 'REMOTE_ADDR' ); } return $realip; } function array2json($arr) { if (function_exists('json_encode')) return json_encode($arr); $keys = array_keys($arr); $isarr = true; $json = ""; for($i=0;$i!i", "[img $1/]", $content); $content = str_replace(array('<', '>'), array('<', '>'), $content); $content = preg_replace("!\[img (.*?)/\]!i", " ", $content); $content = str_replace($lang['ban'], '', $content); $content = ($style)?"{$content}":$content; $ubbarray = array('[:ani_wink:]', '[:big_eyes:]', '[:cool:]', '[:cry:]', '[:eye_roll:]', '[:grin:]', '[:happy:]', '[:not_impressed:]', '[:smile:]', '[:smile_eyes:]', '[:stickout:]', '[:straight:]', '[:surprised:]', '[:unhappy:]', '[:wink:]'); $content = str_replace($ubbarray, array('

安装说明:
因为这一款php+ajax实时聊天室的聊天记录是保存到PHP文件中的,所以不用导入数据库,安装自然也就方便多了,只需要将下载的文件包解压缩到可以运行PHP的根目录下即可.
