一、websocket

    客户端完整源码查看:view-source:http://zixuephp.net/chat.html

    websocket客户端:

//client.html
$(function(){    
var wsname = $('.wsname1').text();    
var wsimg = $('.chatheadimg').attr('src');    
var wsServer = 'ws://106.12.107.148:9501';    
var websocket = new WebSocket(wsServer);    
websocket.onopen = function (event) {    
layer.msg('聊天室连接成功!');    
websocket.send('{"type":"1","name":"'+wsname+'","msg":"上线了!","self":"0","img":"'+wsimg+'"}');    
};    
websocket.onclose = function (event) {    
//console.log("连接关闭!");    
websocket.send('{"type":"3","name":"'+wsname+'","msg":"下线了!","self":"0","img":"'+wsimg+'"}');    
};    
websocket.onmessage = function (event) {    
//console.log(event.data);    
var chatmessage = JSON.parse(event.data);    
if(chatmessage){    
var ctype = chatmessage['type'];    
var cself = chatmessage['self'];    
var cname = chatmessage['name'];    
var ctime = chatmessage['time'];    
var cmsg = chatmessage['msg'];    
var cimg = chatmessage['img'];    
var person = chatmessage['person'];    
if(ctype == 1){    
if( cself== 0){    
layer.msg('【'+cname+'】'+cmsg);    
}    
$('.persion1').text(person);    
}else if (ctype == 2){    
var html ='';    
if( cself == 1){    
html = "<div class=\"clearfix chatmessage\">\n" +    
"                                    <div class=\"chatnametime rrn\">\n" +    
"                                            <span>"+cname+"</span>&nbsp;&nbsp;\n" +    
"                                            <span>"+ctime+"</span>\n" +    
"                                    </div>\n" +    
"                                    <div class=\"chatimgcon\">\n" +    
"                                        <div class=\"fr\">\n" +    
"                                            <img src=\""+cimg+"\" />" +    
"                                        </div>\n" +    
"                                        <div class=\"fr chcon\">"+cmsg+"</div>\n" +    
"                                    </div>\n" +    
"                                </div>";    
}else{    
html = "<div class=\"clearfix chatmessage\">\n" +    
"                                    <div class=\"chatnametime\">\n" +    
"                                            <span>"+cname+"</span>&nbsp;&nbsp;\n" +    
"                                            <span>"+ctime+"</span>\n" +    
"                                    </div>\n" +    
"                                    <div class=\"chatimgcon\">\n" +    
"                                        <div class=\"fl\">\n" +    
"                                            <img src=\""+cimg+"\" />\n" +    
"                                        </div>\n" +    
"                                        <div class=\"fl chcon\">"+cmsg+"</div>\n" +    
"                                    </div>\n" +    
"                                </div>";    
}    
$('.chatdetails').append(html);    
$('.persion1').text(person);    
$(".chatdetails").animate({scrollTop:$('.chatdetails')[0].scrollHeight},200);    
}else if(ctype == 3){    
$('.persion1').text(person);    
layer.msg('【'+cname+'】'+cmsg);    
}    
}    
};    
websocket.onerror = function (event, e) {    
layer.msg('聊天室错误'+event.data);    
};    
$(".chatsend").click(function(){    
var chatcon = '';    
chatcon = $('.chatcontent textarea').val();    
websocket.send('{"type":"2","name":"'+wsname+'","msg":"'+chatcon+'","self":"0","img":"'+wsimg+'"}');    
});    
window.onunload = function() {    
websocket.send('{"type":"3","name":"'+wsname+'","msg":"下线了!","self":"0","img":"'+wsimg+'"}');    
}    
});

二、php swoole

    swoole服务端:

    需要安装php swoole扩展才能运行。编译安装的php如果没有swoole扩展的安装方法:http://zixuephp.net/article-430.html

//server.php
//创建websocket服务器对象,监听0.0.0.0:9501端口
$ws = new swoole_websocket_server("0.0.0.0", 9501);

//监听WebSocket连接打开事件
$ws->on('open', function ($ws, $request) {
    //var_dump($request->fd);
    //var_dump($request->get);
    //var_dump($request->server);
    //$ws->push($request->fd, $request->fd);
});

//监听WebSocket消息事件
$ws->on('message', function ($ws, $frame) {
    $message = '';
    $message = $frame->data;
    $person = count($ws->connections);
    foreach($ws->connections as $fd){
        if($fd == $frame->fd){
            $message = json_decode($message,true);
            $message['self'] =1;
            $message['time'] =date('Y-m-d H:i:s',time());
            $message['person'] = $person;
            $message = json_encode($message);
            $ws->push($fd,$message);
        }else{
            $message = json_decode($message,true);
            $message['self'] =0;
            $message['time'] =date('Y-m-d H:i:s',time());
            $message['person'] = $person;
            $message = json_encode($message);
            $ws->push($fd, $message);
        }
    }
    //echo "message:".$message."\n";
});

//监听WebSocket连接关闭事件
$ws->on('close', function ($ws, $fd) {
    //echo "client-{$fd} is closed\n";
});

$ws->start();

三、php运行服务端

    nohup /usr/bin/php server.php &

[root@zixuephp /]# whereis php
php: /usr/bin/php /usr/local/php
[root@zixuephp /]# nohup /usr/bin/php server.php &
