Barrage, a popular Chinese term, refers to the comment subtitles that pop up when watching vi d eos on the Internet. Let's take a look at how to use workerman to implement a simple barrage.
php code:
<?php
use Workerman\Worker;
require_once '../Autoloader.php';//Note that it depends on where this file is in your workerman and is being modified
$global_uid = 0;
// Allocate uid when the client connects, save the connection, and notify all clients
function handle_connection($connection) {
global $text_worker, $global_uid;
// Assign a uid to this link
$connection->uid = ++$global_uid;
foreach ($text_worker->connections as $conn) {
$conn->send("user[{$connection->uid}] online");
}
}
// When the client sends a message, it forwards it to everyone
function handle_message($connection, $data) {
global $text_worker;
foreach ($text_worker->connections as $conn) {
$conn->send("user[{$connection->uid}] said: $data");
}
}
// Broadcast to all clients when the client is disconnected
function handle_close($connection) {
global $text_worker;
foreach ($text_worker->connections as $conn) {
$conn->send("user[{$connection->uid}] logout");
}
}
$text_worker = new Worker("websocket://0.0.0.0:2347");
$text_worker->count = 1;
$text_worker->onConnect = 'handle_connection';
$text_worker->onMessage = 'handle_message';
$text_worker->onClose = 'handle_close';
Worker::runAll();
HTML code:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Simple Chat</title>
</head>
<body>
<center>
<h1>Simple Chat</h1>
<input type="text" id="msg">
<button type="button" id="send">send</button>
<div id="content" style="width:200px;height:200px;border:1px solid red">
//Pretend to be playing video
<marquee behavior="" direction=""></marquee>
</div>
</center>
</body>
<script type="text/javascript">
window.onload = function () {
var ws = new WebSocket("ws://127.0.0.1:2347");
document.getElementById("send").onclick = function () {
var msg = document.getElementById("msg").value;
ws.send(msg);
};
ws.onopen = function () {
console.log("Successful connection");
// ws.send('raid');
};
ws.onmessage = function (e) {
document.getElementById("content").innerHTML += '<marquee behavior="" direction="">' + e.data + '</marquee>';
};
};
</script>
</html>
