椭圆曲线加密PHP:传递给_构造（）的可捕获致命错误参数1

我正在尝试使用Matyas Danter的phpecc库使用椭圆曲线加密，该库可在中找到。然而，当我创建变量Alice时，我得到了以下错误，尽管传递的参数是一个点。。请帮忙

可捕获的致命错误：传递给EcDH的参数1:：_construct（）必须是Point的实例，字符串给定，在第31行的C:\xampp\htdocs\ECC-example.php中调用，并在第39行的C:\xampp\htdocs\classes\EcDH.php中定义

NISTcurve.php具有以下功能：

         public static function generator_192() {
         // NIST Curve P-192:
        if (extension_loaded('gmp') && USE_EXT == 'GMP') {
        $_p = '6277101735386680763835789423207666416083908700390324961279';
        $_r = '6277101735386680763835789423176059013767194773182842284081';
        $_b = gmp_Utils::gmp_hexdec('0x64210519e59c80e70fa7e9ab72243049feb8deecc146b9b1');
        $_Gx = gmp_Utils::gmp_hexdec('0x188da80eb03090f67cbf20eb43a18800f4ff0afd82ff1012');
        $_Gy = gmp_Utils::gmp_hexdec('0x07192b95ffc8da78631011ed6b24cdd573f977a11e794811');

        $curve_192 = new CurveFp($_p, -3, $_b);
        $generator_192 = new Point($curve_192, $_Gx, $_Gy, $_r);
    } else if (extension_loaded('bcmath') && USE_EXT == 'BCMATH') {
        $_p = '6277101735386680763835789423207666416083908700390324961279';
        $_r = '6277101735386680763835789423176059013767194773182842284081';
        $_b = bcmath_Utils::bchexdec('0x64210519e59c80e70fa7e9ab72243049feb8deecc146b9b1');
        $_Gx = bcmath_Utils::bchexdec('0x188da80eb03090f67cbf20eb43a18800f4ff0afd82ff1012');
        $_Gy = bcmath_Utils::bchexdec('0x07192b95ffc8da78631011ed6b24cdd573f977a11e794811');

        $curve_192 = new CurveFp($_p, -3, $_b);
        $generator_192 = new Point($curve_192, $_Gx, $_Gy, $_r);
    }
    return $generator_192;
}

---

错误在最后一行

$Alice=新EcDH（g）->错误

$Alice=新的EcDH（$g）->正确

一个愚蠢的错误导致了一个巨大的错误
