Stripe success page trying to get details from session_id - php

Question

I'm trying to just retrieve the details from a successful transaction from Stripe in php. The official documentation tells me to install and use Slim, something I can't do in my current situation.
So far I've got the following code which throws me a report of some kind, but i don't fully understand what i'm looking at and I'm not sure where to go from here, or even if I'm getting the right information back in the first place!
<?php
error_reporting(E_ALL);
ini_set('display_errors', 'on');
require_once('../../stripe/init.php');
$stripe = new \Stripe\StripeClient(
'[my test key]'
);
$stripe->checkout->sessions->retrieve(
$_GET['session_id'],
[]
);
echo "<pre>";
print_r($stripe);
echo "</pre>";
?>
this give me the following:
Stripe\Service\Checkout\SessionService Object
(
[client:protected] => Stripe\StripeClient Object

[coreServiceFactory:Stripe\StripeClient:private] => Stripe\Service\CoreServiceFactory Object

Answer 1

I worked it out based on the code I originally had. Here it is so other people don't have to go through the frustration I had:
require_once('../../stripe/init.php');
$stripe = new \Stripe\StripeClient(
'{{my api key}}'
);
$line_items = $stripe->checkout->sessions->retrieve(
$_GET['session_id'],
[]
);
echo "<pre>";
print_r($line_items);
echo "</pre>";
I just needed to put the retrieve into an object, then I can output that object in the form of a json. Or something like that anyway. You'll know what I mean when you try it.

There you go
require 'vendor/autoload.php';
\Stripe\Stripe::setApiKey('sk_test_Your_Test_Key');
$session = \Stripe\Checkout\Session::retrieve($_GET['session_id']);
$customer = \Stripe\Customer::retrieve($session->customer);
print_r($customer);
