php_network_getaddresses: getaddrinfo failed: No address associated with hostname(0) Warning: fclose(): supplied argument is not a valid stream resource

이 오류가 발생해서 그런데

현재 소스코드를 보니

$fp = @fsockopen($host,80,$errno,$errstr,30);
    $return = "";
    if (!$fp) {
        echo $errstr."(".$errno.")";
    } else {
        fputs($fp, "POST ".$path." HTTP/1.1\r\n");
        fputs($fp, "Host: ".$host."\r\n");
        fputs($fp, "Content-type: application/x-www-form-urlencoded\r\n");
        fputs($fp, "Content-length: ".strlen($param)."\r\n");
        fputs($fp, "Connection: close\r\n\r\n");
        fputs($fp, $param."\r\n\r\n");
        while(!feof($fp)) $return .= fgets($fp,4096);
    }

fclose ($fp);

이렇게 작성되어있는데 

$fp = @fsockopen($host,80,$errno,$errstr,30);
    $return = "";
    if (!$fp) {
        echo $errstr."(".$errno.")";
    } else {
        fputs($fp, "POST ".$path." HTTP/1.1\r\n");
        fputs($fp, "Host: ".$host."\r\n");
        fputs($fp, "Content-type: application/x-www-form-urlencoded\r\n");
        fputs($fp, "Content-length: ".strlen($param)."\r\n");
        fputs($fp, "Connection: close\r\n\r\n");
        fputs($fp, $param."\r\n\r\n");
        while(!feof($fp)) $return .= fgets($fp,4096);

        fclose ($fp);
    }

fclose($fp)를 else문에 넣으면 오류가 수정될까요..??
