How to Set Up Stripe Payments in PHP in 2025

Stripe is the gold standard for online payments and their PHP SDK makes integration straightforward. In this guide, we will walk through a complete integration from installation to handling webhooks in production.

Prerequisites

PHP 8.1+
Composer installed
Stripe account (free to create)

Step 1 — Install the SDK

composer require stripe/stripe-php

Step 2 — Create a Payment Intent

$stripe = new StripeStripeClient(STRIPE_SECRET_KEY);
$intent = $stripe->paymentIntents->create([
  "amount" => 2999,
  "currency" => "usd",
  "automatic_payment_methods" => ["enabled" => true],
]);

Step 3 — Handle the Webhook

Webhooks are essential for confirming payments server-side. Always verify the signature...

Set your webhook URL in the Stripe Dashboard to https://yoursite.com/payment/stripe-webhook.php and listen to payment_intent.succeeded.

Testing

Use test card 4242 4242 4242 4242 with any future expiry and CVV.
