功能不正常

Question

我的php功能效果不佳：

public function authorize(Varien_Object $payment, $amount)
    {
        require_once Mage::getModuleDir('', 'Spectrocoin_Spectrocoin') . DS . 'lib' . DS . 'SCMerchantClient' . DS . 'SCMerchantClient.php';
        $privateKeyFilePath = Mage::getBaseDir('media') . '/spectrocoin/keys/' . Mage::getStoreConfig('payment/Spectrocoin/private_key_file');
        $merchantId = Mage::getStoreConfig('payment/Spectrocoin/merchant_id');
        $appId = Mage::getStoreConfig('payment/Spectrocoin/app_id');
        if (!file_exists($privateKeyFilePath) || !is_file($privateKeyFilePath)
            || !$merchantId || !$appId) {
            echo 'Spectrocoin is not fully configured. Please select different payment';
            exit;
        }

直到if我认为一切都很好，因为如果我粘贴出口直到if它起作用但在if之后没有任何作用我尝试退出，打印没有帮助...... / p>
