First download workerman https://www.workerman.net/download (Recommended learning: workerman tutorial)
After downloading, create a new file start.php under the workerman file
##The code is as follows
<?php
use Workerman\Worker;
//Autoloader.php路徑
require_once "./Autoloader.php";
$global_uid = 0;
// 當(dāng)客戶端連上來時(shí)分配uid，并保存連接，并通知所有客戶端
function handle_connection($connection)
{
global $text_worker, $global_uid;
// 為這個(gè)連接分配一個(gè)uid
$connection->uid = ++$global_uid;
}
// 當(dāng)客戶端發(fā)送消息過來時(shí)，轉(zhuǎn)發(fā)給所有人
function handle_message($connection, $data)
{
global $text_worker;
foreach($text_worker->connections as $conn)
{
$conn->send("user[{$connection->uid}] said: $data");
}
}
// 當(dāng)客戶端斷開時(shí)，廣播給所有客戶端
function handle_close($connection)
{
global $text_worker;
foreach($text_worker->connections as $conn)
{
$conn->send("user[{$connection->uid}] logout");
}
}
// 創(chuàng)建一個(gè)文本協(xié)議的Worker監(jiān)聽2000接口 用0.0.0.0方便鏈接內(nèi)網(wǎng)外網(wǎng)
$text_worker = new Worker("websocket://0.0.0.0:2000");
// 只啟動(dòng)1個(gè)進(jìn)程，這樣方便客戶端之間傳輸數(shù)據(jù)
$text_worker->count = 1;
$text_worker->onConnect = 'handle_connection';
$text_worker->onMessage = 'handle_message';
$text_worker->onClose = 'handle_close';
Worker::runAll();Then run the command line php start.php start
Simple test is to open the browser and press F12 to open it Debug the console, enter in the Console column (or put the following code into the html page and run it with js
// 假設(shè)服務(wù)端ip為127.0.0.1
ws = new WebSocket("ws://127.0.0.1:2000");
ws.onopen = function() {
alert("連接成功");
ws.send('我是誰？');
alert("給服務(wù)端發(fā)送一個(gè)字符串：我是誰？");
};
ws.onmessage = function(e) {
alert("收到服務(wù)端的消息：" + e.data);
};
