NOTE

Always handle errors when you use stripe functions. You don't want to make mistakes when it comes to people's money.

Create a customer

$stripe_client = new Stripe_Client( $user, $stripe_secret, $token );

try {
  $customer = $stripe_client->create_customer();
} catch (Exception $e) {
  //Handle it.  
}

Charge a customer

$stripe_client = new Stripe_Client( $user, $stripe_secret );

//First we get him
try {
    $customer = $stripe_client->retrieve_customer();
} catch ( Exception $e ) {
  //Handle it. 
}

//Now we charge
try {
    $charge = $stripe_client->charge_customer( $customer, 50000, 'Product payment');
} catch ( Exception $e ) {
    //Handle it.
}
