从PHP中的序列化数组中获取元素

Question

我处于通过Paypal Sandbox应用程序接受付款的最后阶段。 '成功'，'paymentID'，'Token'和'PayerID'都可以退货。但是，事务作为序列化数组传递。

当我试图使用的var_dump转储阵列，示出了以下内容：

object(PayPal\Api\Payment)#7 (1) { ["_propMap":"PayPal\Common\PayPalModel":private]=> array(8) { ["id"]=> string(28) "PAY-2XY54251XB3181942KZOPKIA" ["intent"]=> string(4) "sale" ["state"]=> string(8) "approved" ["cart"]=> string(17) "15C96215RJ375133A" ["payer"]=> object(PayPal\Api\Payer)#14 (1) { ["_propMap":"PayPal\Common\PayPalModel":private]=> array(3) { ["payment_method"]=> string(6) "paypal" ["status"]=> string(8) "VERIFIED" ["payer_info"]=> object(PayPal\Api\PayerInfo)#9 (1) { ["_propMap":"PayPal\Common\PayPalModel":private]=> array(7) { ["email"]=> string(20) "test@xxxxxxxxxx" ["first_name"]=> string(4) "Mr" ["last_name"]=> string(7) "Test" ["payer_id"]=> string(13) "4CTHQUQHGE87R" ["shipping_address"]=> object(PayPal\Api\ShippingAddress)#11 (1) { ["_propMap":"PayPal\Common\PayPalModel":private]=> array(6) { ["recipient_name"]=> string(12) "Mr Test" ["line1"]=> string(14) "1 Main Terrace" ["city"]=> string(13) "Wolverhampton" ["state"]=> string(13) "West Midlands" ["postal_code"]=> string(7) "W12 4LQ" ["country_code"]=> string(2) "GB" } } ["phone"]=> string(10) "0358302031" ["country_code"]=> string(2) "GB" } } } } ["transactions"]=> array(1) { [0]=> object(PayPal\Api\Transaction)#13 (1) { ["_propMap":"PayPal\Common\PayPalModel":private]=> array(5) { ["amount"]=> object(PayPal\Api\Amount)#17 (1) { ["_propMap":"PayPal\Common\PayPalModel":private]=> array(3) { ["total"]=> string(4) "5.36" ["currency"]=> string(3) "GBP" ["details"]=> object(PayPal\Api\Details)#19 (1) { ["_propMap":"PayPal\Common\PayPalModel":private]=> array(1) { ["subtotal"]=> string(4) "5.36" } } } } ["description"]=> string(29) "Test Purchase" ["invoice_number"]=> string(24) "INV-PP-2015-12-01-011720" ["item_list"]=> object(PayPal\Api\ItemList)#21 (1) { ["_propMap":"PayPal\Common\PayPalModel":private]=> array(2) { ["items"]=> array(0) { } ["shipping_address"]=> object(PayPal\Api\ShippingAddress)#24 (1) { ["_propMap":"PayPal\Common\PayPalModel":private]=> array(6) { ["recipient_name"]=> string(12) "Mr Test" ["line1"]=> string(14) "1 Main Terrace" ["city"]=> string(13) "Wolverhampton" ["state"]=> string(13) "West Midlands" ["postal_code"]=> string(7) "W12 4LQ" ["country_code"]=> string(2) "GB" } } } } ["related_resources"]=> array(1) { [0]=> object(PayPal\Api\RelatedResources)#26 (1) { ["_propMap":"PayPal\Common\PayPalModel":private]=> array(1) { ["sale"]=> object(PayPal\Api\Sale)#28 (1) { ["_propMap":"PayPal\Common\PayPalModel":private]=> array(11) { ["id"]=> string(17) "49B132929Y668630A" ["state"]=> string(9) "completed" ["amount"]=> object(PayPal\Api\Amount)#30 (1) { ["_propMap":"PayPal\Common\PayPalModel":private]=> array(3) { ["total"]=> string(4) "5.36" ["currency"]=> string(3) "GBP" ["details"]=> object(PayPal\Api\Details)#31 (1) { ["_propMap":"PayPal\Common\PayPalModel":private]=> array(1) { ["subtotal"]=> string(4) "5.36" } } } } ["payment_mode"]=> string(16) "INSTANT_TRANSFER" ["protection_eligibility"]=> string(8) "ELIGIBLE" ["protection_eligibility_type"]=> string(56) "ITEM_NOT_RECEIVED_ELIGIBLE,UNAUTHORIZED_PAYMENT_ELIGIBLE" ["transaction_fee"]=> object(PayPal\Api\Currency)#33 (1) { ["_propMap":"PayPal\Common\PayPalModel":private]=> array(2) { ["value"]=> string(4) "0.38" ["currency"]=> string(3) "GBP" } } ["parent_payment"]=> string(28) "PAY-2XY54251XB3181942KZOPKIA" ["create_time"]=> string(20) "2015-12-01T01:20:56Z" ["update_time"]=> string(20) "2015-12-01T01:20:56Z" ["links"]=> array(3) { [0]=> object(PayPal\Api\Links)#35 (1) { ["_propMap":"PayPal\Common\PayPalModel":private]=> array(3) { ["href"]=> string(65) "https://api.sandbox.paypal.com/v1/payments/sale/49B132929Y668630A" ["rel"]=> string(4) "self" ["method"]=> string(3) "GET" } } [1]=> object(PayPal\Api\Links)#36 (1) { ["_propMap":"PayPal\Common\PayPalModel":private]=> array(3) { ["href"]=> string(72) "https://api.sandbox.paypal.com/v1/payments/sale/49B132929Y668630A/refund" ["rel"]=> string(6) "refund" ["method"]=> string(4) "POST" } } [2]=> object(PayPal\Api\Links)#37 (1) { ["_propMap":"PayPal\Common\PayPalModel":private]=> array(3) { ["href"]=> string(79) "https://api.sandbox.paypal.com/v1/payments/payment/PAY-2XY54251XB3181942KZOPKIA" ["rel"]=> string(14) "parent_payment" ["method"]=> string(3) "GET" } } } } } } } } } } } ["create_time"]=> string(20) "2015-12-01T01:20:56Z" ["links"]=> array(1) { [0]=> object(PayPal\Api\Links)#39 (1) { ["_propMap":"PayPal\Common\PayPalModel":private]=> array(3) { ["href"]=> string(79) "https://api.sandbox.paypal.com/v1/payments/payment/PAY-2XY54251XB3181942KZOPKIA" ["rel"]=> string(4) "self" ["method"]=> string(3) "GET" } } } } } 

我试图获取值“INVOICE_NUMBER”，从该字符串没有“ID”和“量”可用，所以我可以使用这些值，并且当购买被批准时，充值人帐户。

这是我的代码，请你解释我错了，因为我很迷路？

<?php 

use PayPal\Api\Payment; 
use PayPal\Api\PaymentExecution; 

require 'paypalapp/start.php'; 

if (!isset($_GET['success'], $_GET['paymentId'], $_GET['PayerID'])) { 
header("Location: http://www.domain.co.uk/fail.php"); 

} 

if ((bool)$_GET['success'] === false) { 
header("Location: http://www.domain.co.uk/fail.php"); 
} 

$paymentId = $_GET['paymentId']; 
$payerId = $_GET['PayerID']; 
$payment = Payment::get($paymentId, $paypal); 

$execute = new PaymentExecution(); 
$execute->setPayerId($payerId); 

try { 
    $result = $payment->execute($execute, $paypal); 
} catch (Exception $e) { 
    $data = json_decode($e->getData()); 
    echo $data->message; 
} 

var_dump($payment); 

echo 'Payment Made. Thanks!'; 

?> 

干杯！

正如在评论中指出，你只需要unserialize()响应对象：

$getval = unserialize($payment); 
echo $getval->id; 

^{注：作为返回一个对象，你需要访问它作为一个对象（-> ）而不是数组（[]）。}
