if $event->type stripe webhook 解析错误

Question

我正在使用以下代码作为条带 webhook 从 phpmailer 向用户发送 cutsom 电子邮件。来自this gist。

我似乎无法弄清楚为什么会出现这个错误，我很少使用 php，所以我确定这是我不熟悉的东西，这是我收到的错误。

解析错误：语法错误，意外的 '$event' (T_VARIABLE)，在第 24 行的 /usr/share/nginx/html/emailReceipt.php 中需要 '('

代码

<?php

// SETUP:
// 1. Customize all the settings (stripe api key, email settings, email text)
// 2. Put this code somewhere where it's accessible by a URL on your server.
// 3. Add the URL of that location to the settings at https://manage.stripe.com/#account/webhooks
// 4. Have fun!

// set your secret key: remember to change this to your live secret key in production
// see your keys here https://manage.stripe.com/account
//Stripe::setApiKey("YOUR STRIPE SECREY KEY");
Stripe::setApiKey("sk_test_WggOmz2smwT9nGdx7aos2R5Q");


// retrieve the request's body and parse it as JSON
$body = @file_get_contents('php://input');
$event_json = json_decode($body);

// for extra security, retrieve from the Stripe API
$event_id = $event_json->id;
$event = Stripe_Event::retrieve($event_id);

// This will send receipts on succesful invoices
if $event->type == 'invoice.payment_succeeded' {
  email_invoice_receipt(event->data->object);
}

function email_invoice_receipt($invoice) {
  $customer = Stripe_Customer::retrieve($invoice->customer);

  //Make sure to customize your from address
  $subject = 'Your payment has been received';
  $headers = 'From: "MyApp Support" <support@myapp.com>';

  mail($customer->email, $subject, message_body(), $headers);
}

function format_stripe_amount($amount) {
  return sprintf('$%0.2f', $amount / 100.0);
}

function format_stripe_timestamp($timestamp) {
  return strftime("%m/%d/%Y", $timestamp);
}

function payment_received_body($invoice, $customer) {
  $subscription = $invoice->lines->subscriptions[0];
  return <<'EOF'
Dear {$customer->email}:

This is a receipt for your subscription. This is only a receipt,
no payment is due. Thanks for your continued support!

-------------------------------------------------
SUBSCRIPTION RECEIPT

Email: {$customer->email}
Plan: {$subscription->plan->name}
Amount: {format_stripe_amount($invoice->total)} (USD)

For service between {format_stripe_timestamp($subscription->period->start)} and {format_stripe_timestamp($subscription->period->end)}

-------------------------------------------------

EOF;
}

?>

您的if 语句中缺少大括号：

if $event->type == 'invoice.payment_succeeded'

应该是：

if ($event->type == 'invoice.payment_succeeded')
