php - php 中定期付款的 PayPal 订阅

Question

$paypalURL = 'https://www.sandbox.paypal.com/cgi-bin/webscr'; //Test PayPal API URL
$paypalID = ''; //Business Email
$usermail = $idarray->email;
                     <form action="<?php echo $paypalURL; ?>" method="post">
                     <!-- Identify your business so that you can collect the payments. -->
                     <input type="hidden" name="business" value="<?php echo $paypalID; ?>">
