本文實(shí)例講述了PHP使用swoole編寫簡單的echo服務(wù)器。分享給大家供大家參考，具體如下：

server.php代碼如下：

<?phpclass EchoServer { protected $serv = null; public function __construct() { $this->serv = new swoole_server(’0.0.0.0’, 8888); //配置參數(shù) $this->serv->set(array( ’worker_num’ => 4, ’daemonize’ => 0, )); //注冊回調(diào)函數(shù) $this->serv->on(’start’, array($this, ’start’)); $this->serv->on(’connect’, array($this, ’connect’)); $this->serv->on(’receive’, array($this, ’receive’)); $this->serv->on(’close’, array($this, ’close’)); //啟動(dòng)服務(wù) $this->serv->start(); } public function start($serv) { echo 'start n'; } //有客戶端連接時(shí) public function connect($serv, $fd) { echo 'connect n'; $serv->send($fd, 'hello n'); } public function close($serv, $fd) { echo 'close n'; } public function receive($serv, $fd, $from_id, $data) { echo 'get message {$fd} : {$data} n'; //向客戶端發(fā)送信息 $serv->send($fd, $data . 'n'); }} $serv = new EchoServer();

client.php代碼如下：

<?phpclass EchoClient { protected $client = null; public function __construct() { //注意這里需設(shè)置為異步，不然下面無法設(shè)置事件回調(diào)函數(shù) $this->client = new swoole_client(SWOOLE_SOCK_TCP, SWOOLE_SOCK_ASYNC); $this->client->on(’connect’, array($this, ’connect’)); $this->client->on(’receive’, array($this, ’receive’)); $this->client->on(’close’, array($this, ’close’)); $this->client->on(’error’, array($this, ’error’)); //連接服務(wù)端 $this->client->connect(’0.0.0.0’, 8888); } public function connect($client) { echo 'connect n'; } public function receive($client, $data) { echo 'server send: {$data}'; //向標(biāo)準(zhǔn)輸出寫入數(shù)據(jù) fwrite(STDOUT, '請輸入消息：'); //獲取標(biāo)準(zhǔn)輸入數(shù)據(jù) $msg = trim(fgets(STDIN)); //向服務(wù)端發(fā)送數(shù)據(jù) $client->send($msg); } public function close($client) { echo 'close n'; } public function error($client) { echo 'error n'; }} $cli = new EchoClient();

然后分別運(yùn)行這兩個(gè)腳本

運(yùn)行結(jié)果如下：
