本文实例讲述了PHP使用swoole编写简单的echo服务器。分享给大家供大家参考，具体如下：

server.php代码如下：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 <?php class EchoServer { protected $serv = null; public function __construct() { $this ->serv = new swoole_server( '0.0.0.0' , 8888); //配置参数 $this ->serv->set( array ( 'worker_num' => 4, 'daemonize' => 0, )); //注册回调函数 $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' )); //启动服务 $this ->serv->start(); } public function start( $serv ) { echo "start \n" ; } //有客户端连接时 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" ; //向客户端发送信息 $serv ->send( $fd , $data . "\n" ); } } $serv = new EchoServer();

client.php代码如下：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 <?php class EchoClient { protected $client = null; public function __construct() { //注意这里需设置为异步，不然下面无法设置事件回调函数 $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' )); //连接服务端 $this ->client->connect( '0.0.0.0' , 8888); } public function connect( $client ) { echo "connect \n" ; } public function receive( $client , $data ) { echo "server send: {$data}" ; //向标准输出写入数据 fwrite(STDOUT, "请输入消息：" ); //获取标准输入数据 $msg = trim( fgets (STDIN)); //向服务端发送数据 $client ->send( $msg ); } public function close( $client ) { echo "close \n" ; } public function error( $client ) { echo "error \n" ; } } $cli = new EchoClient();
