Question

所以我得到了print_r的下一个输出

Coinbase\Wallet\Value\Money Object
(
    [amount:Coinbase\Wallet\Value\Money:private] =>  18945.00
    [currency:Coinbase\Wallet\Value\Money:private] =>  USD
)

我使用的是Coinbase SDK - ＆gt; link to github

我的问题是我应该如何阅读金额值？我正在使用

生成它

$buyPrice = $client->getSpotPrice('BTC-USD');

和getSpotPrice函数是 - ＆gt;

 public function getSpotPrice($currency = null, array $params = [])
{
    if (strpos($currency, '-') !== false) {
        $pair = $currency;
    } else if ($currency) {
        $pair = 'BTC-' . $currency;
    } else {
        $pair = 'BTC-USD';
    }

    return $this->getAndMapMoney('/v2/prices/' . $pair . '/spot', $params);
}

在测试集成中看到类似的东西，但我无法告诉如何使这项工作：

public function testGetSpotPrice1()
{
    $price = $this->client->getSpotPrice();

    $this->assertInstanceOf(Money::class, $price);
}

任何帮助/想法将不胜感激，谢谢！

一旦你获得了

的价值

$buyPrice = $client->getSpotPrice('BTC-USD');

然后您可以使用（来自来源https://github.com/coinbase/coinbase-php/blob/master/src/Value/Money.php）...

$amount = $buyPrice->getAmount();
$currency = $buyPrice->getCurrency();

$BTCSellPrice = $client->getSpotPrice('BTC-USD');

//this is what you are looking for
