Need Quick Working Example of Stripe SetupIntent Process for PHP

Hi there. I need a quick working example of using SetupIntent to save a credit card for an existing Stripe Customer ID. See this example: [login to view URL] I use the Stripe PHP SDK, so if it was done in that style that would be great. For example: // Create new customer $customer = \Stripe\Customer::create([ 'source' => $_POST['token'], 'email' => $user['email'], 'description' => $user['name'], // 'customer' => 'cus_xxx', ]); $paymentMethod = \Stripe\PaymentMethod::create([ 'type' => 'card', 'card' => [ 'number' => $_POST['token'], 'exp_month' => $_POST['exp_month'], // Replace with your form's exp_month 'exp_year' => $_POST['exp_year'], // Replace with your form's exp_year 'cvc' => $_POST['cvc'], // Replace with your form's cvc ], ]); The part I really have trouble with is posting the token in a way where I can easily retrieve it and use it for saving the card or setting up a paymentintent with the card, etc. Also, I'm not sure if the credit card object is part of the token object or not. It seems like some examples I see pass the credit card as a single object from the same process that creates the token and other examples I see maybe break out the credit card and the token id from the same token object. I had an old dev who posted the token via Ajax to PHP for me for one feature and that was great, so it would be helpful to have a couple of examples of how I can pass and handle the token and the credit card variables. I've attached some example files from my code and here's a link to the js files I'm using: [login to view URL] I can pay $50 for this. Thanks!
