php之与python进行socket通信

## 设计目的

通过前端页面发起请求交给php，php创建socket请求交给python脚本，然后执行完毕之后，返回给前端。

关闭服务

## service / main.php

sendMsg($req);
$ret = $con->getMsg();
echo $ret;
?>

## service / mysocket.php

conn = socket_create(AF_INET,SOCK_STREAM,SOL_TCP)) < 0) 
			{
				echo "socket_create() 失败的原因是:".socket_strerror($this->conn)."\n";
			}

			$result = socket_connect($this->conn, $ip, $port);
			if ($result < 0) {
			    echo "socket_connect() failed.\nReason: ($result) " . socket_strerror($result) . "\n";
			}else {
			    echo "连接OK\n";
			}
	}
	public static function getInstance()
	{
		if(is_null(self::$instance))
		{
			self::$instance = new Connector;  
		}
		return self::$instance;
	}
	public function sendMsg($msg)
	{
		socket_write($this->conn,$msg);
	}
	public function getMsg()
	{
		$clients = array($this->conn);
		while(true)
		{
			$read = $clients;
			$wrSet = NULL;
			$errSet = NULL;
			if(socket_select($read, $wrSet,$errSet, 3) < 1)
			{
				continue;
			}
			foreach($read as $read_sock)
			{
				$data = @socket_read($read_sock,1024,PHP_BINARY_READ);
				socket_close($this->conn);
				return $data;
			}
		}

# Now, you can use telnet to test it, the command is "telnet 127.0.0.1 9011"
# You also can use web broswer to test, input the address of "http://127.0.0.1:9011" and press Enter button
# Enjoy it....
