PHP开发实时聊天系统的相关技术和框架介绍
导语:实时聊天系统在现代社交网络中已经成为一项必不可少的功能。本文将介绍PHP开发实时聊天系统所需的相关技术和框架,并提供代码示例供读者参考。
一、相关技术概述
二、相关框架介绍
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();
三、总结
