这篇文章结合实例主要介绍了PHP实现简单的聊天室功能，有一定的参考价值，感兴趣的朋友可以参考一下，希望对你有所帮助！
前端部分：
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>聊天室</title>
</head>
<style>
#set_name{
margin: auto;
text-align: center;
}
</style>
<body>
<h3 style="text-align: center">亮亮的聊天室</h3>
<div id="set_name">
姓名:<input name="name" id="name"><input type="button" onclick="set_name();" value="进入群聊">
</div>
<div id="chat" style="width: 600px; border: red 1px solid;margin: auto;display: none">
<div id="sayContent" style="height: 300px;border-bottom: silver 1px dashed;">
</div>
<div style="height: 75px;margin-top: 10px">
<textarea id="content" style="height: 50px;width: 480px;background-color: #00a0e9;float: left;"></textarea>
<button id="submit" style="float: right;height: 55px;width:50px;margin-right:45px;display: block;" onclick="send_msg();">发送</button>
</div>
</div>
<script>
var name = ws = '' ;
//执行websock
function chat() {
var wsserver = 'ws://47.94.11.195:443';
//调用WebSocket对象建立连接
//ws wss: // ip:port(字符串)
ws = new WebSocket(wsserver);
//获取聊天内容展示窗口
var sayContent = document.getElementById('sayContent');
//onopen监听连接打开
ws.onopen = function (v) {
var user = new Object();
user.name = name;
user.type = 1;//对用户设置姓名
var json = JSON.stringify(user);
ws.send(json);//发送数据
}
//onmessage监听服务器数据推送
ws.onmessage = function (v) {
var html = sayContent.innerHTML;
sayContent.innerHTML = html + "<br>"+v.data;
}
//监听连接关闭
ws.onclose = function (v) {
var html = sayContent.innerHTML;
sayContent.innerHTML = html + "<br>聊天室已关闭!";
}
}
//设置用户名
function set_name() {
name = document.getElementById('name').value;
if(name == ''){
alert('请输入用户名!');
return false;
}
document.getElementById('set_name').style.display='none';
document.getElementById('chat').style.display='block';
chat();
}
function send_msg() {
var content = document.getElementById('content');
if(content.value == ''){
alert('请输入聊天内容!');
return false;
}
var msg = new Object();
msg.content = content.value;
msg.type = 2;
var str = JSON.stringify(msg);
ws.send(str);
}
</script>
</body>
</html>后台部分：
<?php
$server = new swoole_websocket_server("0.0.0.0", 443);
$server->users = [];
$server->on('open', function (swoole_websocket_server $server, $request) {
$server->users[$request->fd]['id'] = $request->fd;
});
$server->on('message', function (swoole_websocket_server $server, $frame) {
$data = json_decode($frame->data,true);
if($data['type'] == 1){
$server->users[$frame->fd]['name']=$data['name'];
$server->push($frame->fd,'欢迎您('.$data['name'].')进入聊天室!');
}else{
foreach($server->users as $v){
$server->push($v['id'], $server->users[$frame->fd]['name'].'说:'.$data['content']);
}
}
});
$server->on('close', function ($ser, $fd) {
file_put_contents('qq.txt',$server->users[$frame->fd],FILE_APPEND);
unset($server->users[$frame->fd]);
});
$server->start();更多相关教程请访问 php编程从入门到精通全套视频教程
