這一上機實驗的開發環境用的是jetbrain公司的phpstormphp

上級步驟以下：css

建立websocket服務端

<?php $server = new swoole_websocket_server('127.0.0.1',9502); function onopen($serv,$request) { echo "成功開啓,已經爲標示符".$request->fd."打開鏈接\n"; } $server->on('open','onopen'); $server->on('message',function(swoole_websocket_server $sw,$frame) { echo "opcode操做符---{$frame->opcode};操做數據---{$frame->data};fd數據來自句柄
---{$frame->fd};finish結束符號{$frame->finish}.\n"; $sw->push($frame->fd,"推送的數據".$frame->data);//數據大小不過2M
}); $server->on('close',function($serv,$fd) { echo "來自{$fd}的通訊結束\n"; }); $server->start(); ?>

準備一個html頁面，並在頁面中附上websocket協議腳本

<!doctype html>
<html lang="en">
<head>
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">
    <meta name="description" content="">
    <meta name="author" content="">

<!-- Bootstrap core JavaScript

在phpstorm中運行寫好的前端頁面----右鍵點擊要運行的html標籤頁，運行Run index.html

運行結果

若是運行多個前端頁面實例將會顯示更多句柄

成功開啓,已經爲標示符1打開鏈接
opcode操做符---1;操做數據---hello server;fd數據來自句柄---1;finish結束符號1.
成功開啓,已經爲標示符2打開鏈接
opcode操做符---1;操做數據---hello server;fd數據來自句柄---2;finish結束符號1.
成功開啓,已經爲標示符3打開鏈接
opcode操做符---1;操做數據---hello server;fd數據來自句柄---3;finish結束符號1.
成功開啓,已經爲標示符4打開鏈接
opcode操做符---1;操做數據---hello server;fd數據來自句柄---4;finish結束符號1.

優化，把服務端封裝成類

class myswserver
{
    const myip = '127.0.0.1';
    const myport = 9502;
    public $serv  = null;
    public function __construct()
    {
        $this->serv = new swoole_websocket_server('127.0.0.1',9502);
        $this->serv->on('open',[$this,'onopen']);#多是swoole特有回調函數形式，能夠對比php魔術方法call_user_func
        $this->serv->on('message',[$this,'onmessage']);
        $this->serv->on('close',[$this,'onclose']);
        $this->serv->start();
    }

    public function onopen($serv,$request)
    {
        echo "鏈接{$request->fd}已經創建\n";
    }
    public function  onmessage($serv,$frame)
    {
        echo "已經爲{$frame->fd}創建了鏈接,併發送了數據{$frame->data},其退出標示符爲{$frame->finish},其opcode爲{$frame->opcode}\n";
        $serv->push($frame->fd,$frame->data);//向客戶端推送數據
    }
    public function onclose($serv,$fd)
    {
        echo "關閉了{$fd}的鏈接\n";
    }
}

$serv = new myswserver();

$serv->start();
