How to Integrate Stripe Payment Gateway in PHP

Step 3.
Edit charge.php file and replace with your Secret Key

try { require_once('Stripe/lib/Stripe.php'); Stripe::setApiKey("secret_key_here"); //Replace with your Secret Key $charge = Stripe_Charge::create(array( "amount" => 1500, "currency" => "usd", "card" => $_POST['stripeToken'], "description" => "Charge for Facebook Login code." ));

try {   require_once('Stripe/lib/Stripe.php');   Stripe::setApiKey("secret_key_here"); //Replace with your Secret Key     $charge = Stripe_Charge::create(array(   "amount" => 1500,   "currency" => "usd",   "card" => $_POST['stripeToken'],   "description" => "Charge for Facebook Login code." ));

Edit index.php file and replace with your Publishable Key

<script src="https://checkout.stripe.com/checkout.js" class="stripe-button" data-key="<em>publishable_key_here</em>" // Replace with your Publishable key data-image="favicon.png" data-name="PHPGang" data-description="Download Script ($15.00)" data-amount="1500"> </script>

<script     src="https://checkout.stripe.com/checkout.js" class="stripe-button"     data-key="<em>publishable_key_here</em>" // Replace with your Publishable key     data-image="favicon.png"     data-name="PHP"     data-description="Download Script ($15.00)"     data-amount="1500"> </script>

The test version does not entail actual transfer of funds and you can teste transfer if you have set up everything necessary to charge a customer by entering the following credit card number: 4242424242424242.
The only thing you would have to worry is Man-in-the-middle attacks and that is why Stripe highly recommends using HTTPS but no data about a card will be stored in your server.
First, we create a basic static web page and create a form that includes a script from Stripe (Checkout.js).

<?php

//let's say each article costs 15.00 bucks

try {
  require_once('Stripe/lib/Stripe.php');
  Stripe::setApiKey("secret_key_here"); //Replace with your Secret Key

  $charge = Stripe_Charge::create(array(
  "amount" => 1500,
  "currency" => "usd",
  "card" => $_POST['stripeToken'],
  "description" => "Charge for Facebook Login code."
));
    //send the file, this line will be reached if no error was thrown above
    echo "<h1>Your payment has been completed. We will send you the Facebook Login code in a minute.</h1>";


//you can send the file to this email:
echo $_POST['stripeEmail'];
}
//catch the errors in any way you like

catch(Stripe_CardError $e) {
   
}


catch (Stripe_InvalidRequestError $e) {
// Invalid parameters were supplied to Stripe's API

} catch (Stripe_AuthenticationError $e) {
// Authentication with Stripe's API failed
// (maybe you changed API keys recently)

} catch (Stripe_ApiConnectionError $e) {
// Network communication with Stripe failed
} catch (Stripe_Error $e) {

// Display a very generic error to the user, and maybe send
// yourself an email
} catch (Exception $e) {

// Something else happened, completely unrelated to Stripe
}
?>

  $charge = Stripe_Charge::create(array(
  "amount" => 1500,
  "currency" => "usd",
  "card" => $_POST['stripeToken'],
  "description" => "Charge for Facebook Login code."
));
