从条带到 PHP 变量的 Json 响应 - Json response from stripe to variables in php

我在php中有一个代码，可以侦听条纹，它会向我的服务器发送json格式的信息。我想从 json 中检索电子邮件并将其分配给变量$email。我不明白我的php代码有什么问题。

PHP代码：

<?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 代码：

实际上，该 JSON 中有 3 封电子邮件。

$event_json = json_decode($input);
$email1 = $event_json->data->object->card->name;
$email2 = $event_json->data->object->receipt_email;
$email3 = $event_json->data->object->source->name;

您可以通过对$event_json进行一系列var_dump陈述来自己弄清楚。

如您所见，名称在对象命名数据中对象命名的对象卡中，因此电子邮件的检索应为：

$email = $event_json->data->object->card->name;
