Json response from stripe to variables in php - php

Question

I have a code in php that listen to stripe which sends to the my server a json format information. I would like to retrieve the email from the json and assign it to a variable $email. I don't understand what is wrong with my php code.
PHP code:
<?php
include "connect.php";
echo "Works";
require_once('stripe_final/init.php');
// Set your secret key: remember to change this to your live secret key in production
// See your keys here https://dashboard.stripe.com/account/apikeys
\Stripe\Stripe::setApiKey("this is hidden key");
$input = #file_get_contents("php://input");
$event_json = json_decode($input);
$event_id = $event_json->id;
if(isset($event_json->id)) {
try {
// to verify this is a real event, we re-retrieve the event from Stripe
// $event = Stripe_Event::retrieve($event_id);
// successful payment
if($event->type == 'charge.succeeded') {
// send a payment receipt email here
// retrieve the payer's information
$email = $event_json->name;
$sql = "INSERT INTO stripe (email) VALUES ('$email')";
if (mysqli_query($db, $sql)) {
echo "New record created successfully";
} else {
echo "Error: " . $sql . "<br>" . mysqli_error($db);
}
mysqli_close($db);
}
} catch (Exception $e) {
}
}
http_response_code(200); // PHP 5.4 or greater
?>
Json code:

Answer 1

Actually, you have 3 emails in that JSON.
$event_json = json_decode($input);
$email1 = $event_json->data->object->card->name;
$email2 = $event_json->data->object->receipt_email;
$email3 = $event_json->data->object->source->name;
You could have figured it out by yourself by doing a series of var_dump statements on $event_json.

Answer 2

As you see name is in object card of object named object in object named data so the retrieval of e-mail should be:
$email = $event_json->data->object->card->name;
