PHP開發即時聊天系統的相關技術和框架介紹
導語:即時聊天系統在現代社交網路中已經成為一項必不可少的功能。本文將介紹PHP開發即時聊天系統所需的相關技術和框架,並提供程式碼範例供讀者參考。
一、相關技術概述
二、相關框架介紹
require 'vendor/autoload.php'; use RatchetMessageComponentInterface; use RatchetConnectionInterface; use RatchetServerIoServer; use RatchetHttpHttpServer; use RatchetWebSocketWsServer; class Chat implements MessageComponentInterface { protected $clients; public function __construct() { $this->clients = new SplObjectStorage; } public function onOpen(ConnectionInterface $conn) { $this->clients->attach($conn); echo "New connection! ({$conn->resourceId}) "; } public function onMessage(ConnectionInterface $from, $msg) { foreach ($this->clients as $client) { $client->send($msg); } } public function onClose(ConnectionInterface $conn) { $this->clients->detach($conn); echo "Connection {$conn->resourceId} has disconnected "; } public function onError(ConnectionInterface $conn, Exception $e) { echo "An error has occurred: {$e->getMessage()} "; $conn->close(); } } $server = IoServer::factory( new HttpServer( new WsServer( new Chat() ) ), 8080 ); $server->run();
$server = new SwooleWebSocketServer("127.0.0.1", 8080); $server->on('open', function (SwooleWebSocketServer $server, $request) { echo "new connection "; }); $server->on('message', function (SwooleWebSocketServer $server, $frame) { foreach ($server->connections as $fd) { $server->push($fd, $frame->data); } }); $server->on('close', function ($ser, $fd) { echo "connection close "; }); $server->start();
