有没有办法在paypal sdk中删除计费方案？

use PayPal\Auth\OAuthTokenCredential;
use PayPal\Rest\ApiContext;
use PayPal\Api\Plan;

// 设置 PayPal REST API 的访问凭据
$clientId = 'YOUR_CLIENT_ID';
$clientSecret = 'YOUR_CLIENT_SECRET';

$apiContext = new ApiContext(
    new OAuthTokenCredential($clientId, $clientSecret)
);

// 设置访问令牌
$apiContext->setAccessToken('YOUR_ACCESS_TOKEN');

// 获取计费方案列表
$planList = Plan::all([], $apiContext);

// 选择要删除的计费方案
$planIdToDelete = 'PLAN_ID_TO_DELETE';

// 查找要删除的计费方案
$planToDelete = array_filter($planList->getPlans(), function ($plan) use ($planIdToDelete) {
    return $plan->getId() === $planIdToDelete;
});

if (count($planToDelete) > 0) {
    // 删除计费方案
    $planToDelete = reset($planToDelete);
    $planToDelete->delete($apiContext);
    echo "计费方案已成功删除。";
} else {
    echo "未找到要删除的计费方案。";
}
