class_implements类不存在

Question

我正在用paysafe (php)实现一个支付系统。

class_implements()：班级退款不存在，也无法加载

我可以创建这样的$r = new Refund()课程退款，但不使用class_implements()。

paysafe的开发人员都在windows下，我在ubuntu上，这与class_implements()有什么不同吗？

$refunds = $this->client->cardPaymentService()->getRefunds(new Refund(array('id' => $p->refund_num)));// class exist
$r = new Refund(); // class exist
class_implements("Refund"); // class_implements(): Class Refund does not exist and could not be loaded
$test = new Pagerator($this->client, $refunds , "Refund"); // class_implements(): Class Refund does not exist and could not be loaded

public function __construct(\Paysafe\PaysafeApiClient $client, $data, $className)
    {
        if (!in_array('Paysafe\Pageable', class_implements($className))) {
            throw new PaysafeException("$className does not implement \Paysafe\Pageable");
        }

        $this->client = $client;

        $this->className = $className;
        $this->arrayKey = call_user_func($className . '::getPageableArrayKey');
        $this->position = 0;

        $this->parseResponse($data);
    }

Answer 1

使用不可加载的类名或非对象调用class_implements将产生警告。

class_implements("Refund"); // class_implements(): Class Refund does not exist and could not be loaded

如果您检查Paysafe库并进入对象定义。

php/blob/master/source/paysafe/CardPayments/Refund.php

您将看到没有自动加载功能。在导入库以支持此功能时，您可能必须亲自对其进行硬编码。

function __autoload($class_name) {
   require_once $class_name . '.php';
}

我们刚刚发布了标签1.03，它修复了一些自动加载问题，如果您仍然有这个问题。

php/commits/master

您还可以使用Packagist回购：php

class_implements在5.1.0之前的版本中不可用--请验证您的服务器正在运行哪个版本的PHP。
