Php 如何在CodeIgniter中配置Paypal

我下载了这个，并用简单的php对它进行了测试，但我不知道将这些文件放在CodeIgniter的哪个文件夹中

任何帮助都将不胜感激。请参阅此

@MohammadImran是的，我跟踪了此链接，但它不在codeigniter中。我应该在哪里保存composer paypal文件？将SDK安装到应用程序文件夹中<代码>编写器需要paypal/paypal checkout sdk 1.0.1

$config['composer\u autoload']

到

TRUE

或自定义路径。如何替换命名空间并使用关键字？他们犯了错误

`Creating an Order
Code:
// Construct a request object and set desired parameters
// Here, OrdersCreateRequest() creates a POST request to /v2/checkout/orders
use PayPalCheckoutSdk\Orders\OrdersCreateRequest;
$request = new OrdersCreateRequest();
$request->prefer('return=representation');
$request->body = [
                     "intent" => "CAPTURE",
                     "purchase_units" => [[
                         "reference_id" => "test_ref_id1",
                         "amount" => [
                             "value" => "100.00",
                             "currency_code" => "USD"
                         ]
                     ]],
                     "application_context" => [
                          "cancel_url" => "https://example.com/cancel",
                          "return_url" => "https://example.com/return"
                     ] 
                 ];

try {
    // Call API with your client and get a response for your call
    $response = $client->execute($request);

    // If call returns body in response, you can get the deserialized version from the result attribute of the response
    print_r($response);
}catch (HttpException $ex) {
    echo $ex->statusCode;
    print_r($ex->getMessage());
}`.
