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
";
 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}
";
 26         $serv->send($fd,$data);
 27 
 28     }
 29 
 30     public function onClose($serv,$fd,$from_id){
 31         echo "client {$fd} close connection 
";
 32     }
 33 
 34 }
 35 
 36 @$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

<?php
class Client
{
    private $client;

    public function __construct() {
        $this->client = new swoole_client(SWOOLE_SOCK_TCP);//同步tcp客户端
    }
    
    public function connect() {
        if( !$this->client->connect("127.0.0.1", 9501 , 1) ) {
            echo "Error: {$this->client->errMsg}[{$this->client->errCode}]
";
        }
        
        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，这里是将提示信息输出到命令行，类似echo
        $msg = trim(fgets(STDIN));//在这里fgets会读取命令行输入的内容，直到读取到换行符或者、EOF或者最大数据量的时候停止读取
        $this->client->send( $msg );

        $message = $this->client->recv();
        echo "Get Message From Server:{$message}
";
    }
}

$client = new Client();
$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}]
";
 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}
";
 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
