swoole1--搭建echo服务器

1.安装swoole :pecl install swoole,然后修改php.ini 开启swoole扩展：extension=swoole.so

2.写一个服务器Server.php

  1 <?php   2    3 class Server{   4     private $serv;   5    6     public function __construct(){   7         $this->serv = new swoole_server("0.0.0.0",9501);   8         $this->serv->set(['worker_num'=>8,'daemonize'=>false]);　　　　　　　//注册服务器回调时间   9         $this->serv->on('Start',[$this,'onStart']);  10         $this->serv->on('Connect',[$this,'onConnect']);  11         $this->serv->on('Receive',[$this,'onReceive']);  12         $this->serv->on('Close',[$this,'onClose']);  13         $this->serv->start();  14     }  15   16     public function onStart($serv){  17         echo "Start\n";  18     }  19   20     public function onConnect($serv,$fd,$from_id){  21         $serv->send($fd,"hello,$fd,欢迎连接");  22     }  23   24     public function onReceive($serv,$fd,$from_id,$data){  25         echo "get message from client {$fd},{$data}\n";  26         $serv->send($fd,$data);  27   28     }  29   30     public function onClose($serv,$fd,$from_id){  31         echo "client {$fd} close connection \n";  32     }  33   34 }  35   36 @$server = new Server();//开了xDebug，这里不用@会弹出警告信息

3.写一个客户端Client.php

 1 <?php  2 class Client  3 {  4     private $client;  5   6     public function __construct() {  7         $this->client = new swoole_client(SWOOLE_SOCK_TCP);//同步tcp客户端  8     }  9      10     public function connect() { 11         if( !$this->client->connect("127.0.0.1", 9501 , 1) ) { 12             echo "Error: {$this->client->errMsg}[{$this->client->errCode}]\n"; 13         } 14          15         fwrite(STDOUT, "请输入消息 Please input msg："); //STDOUT，STDIN : php的伪协议,标准输入（php://stdin）输出(php://stdout)流 16         $msg = trim(fgets(STDIN)); 17         $this->client->send( $msg ); 18  19         $message = $this->client->recv(); 20         echo "Get Message From Server:{$message}\n"; 21     } 22 } 23  24 $client = new Client(); 25 $client->connect();//这里只能收发一次消息后关闭

4.异步客户端

  1 <?php   2    3 class Client{   4     private $client;   5    6     public function __construct(){   7         $this->client = new swoole_client(SWOOLE_SOCK_TCP,SWOOLE_SOCK_ASYNC);//加了异步之后要注册回调，不然报错   8         $this->client->on('connect',[$this,'onConnect']);   9         $this->client->on('receive',[$this,'onReceive']);  10         $this->client->on('error',[$this,'onError']);  11         $this->client->on('close',[$this,'onClose']);  12     }  13   14     public function connect(){  15         if(!$this->client->connect("127.0.0.1",9501,1)){  16             echo "Error :{$this->client->errMsg}[{$this->client->errCode}]\n";  17         }  18     //客户端异步之后就不能再同步发消息  19     //  fwrite(STDOUT,"请输入消息(please input msg):");  20     //  $msg = trim(fgets(STDIN));  21     //  $this->client->send($msg);  22   23     //  $message = $this->client->recv();  24     //  echo "get message from Server:{$message}\n";  25     }  26   27     public function onConnect($cli){  28         $cli->send("hello server ,I'm connect".PHP_EOL);  29     }  30   31     public function onReceive($cli,$data){  32         echo "receive message from server:".$data.PHP_EOL;  33         fwrite(STDOUT,"回复:");  34         $msg = trim(fgets(STDIN));  35         $cli->send($msg);  36     }  37   38     public function onError($cli){  39         echo "Connect faild".PHP_EOL;  40     }  41   42     public function onClose($cli){  43         echo "client connect close".PHP_EOL;  44     }  45   46 }  47   48 $client = new Client();  49 $client->connect();

5.启动Server.php,,Client.php
