How to call APIs from PHP: file_get_contents, cURL, Guzzle and SDKs (code to accompany https://youtu.be/wMyP-q3nPd4)

1-file_get_contents.php

<?php

$payload = json_encode([
    "title" => "Updated title"
]);

$options = [
    "http" => [
        "method" => "PATCH",
        "header" => "Content-type: application/json; charset=UTF-8\r\n" .
                    "Accept-language: en",
        "content" => $payload
    ]
];

$context = stream_context_create($options);

$data = file_get_contents("https://jsonplaceholder.typicode.com/albums/1", false, 
                          $context);

var_dump($data);

print_r($http_response_header);

2-curl.php

<?php

$payload = json_encode([
    "title" => "Updated title"
]);

$headers = [
    "Content-type: application/json; charset=UTF-8",
    "Accept-language: en"
];

$ch = curl_init();

/*
curl_setopt($ch, CURLOPT_URL, "https://jsonplaceholder.typicode.com/albums/1");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
*/
curl_setopt_array($ch, [
    CURLOPT_URL => "https://jsonplaceholder.typicode.com/albums/1",
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_CUSTOMREQUEST => "PATCH",
    CURLOPT_POSTFIELDS => $payload,
    CURLOPT_HTTPHEADER => $headers,
    CURLOPT_HEADER => true
]);

$data = curl_exec($ch);

$status_code = curl_getinfo($ch, CURLINFO_HTTP_CODE);

curl_close($ch);

var_dump($status_code);

var_dump($data);

3-guzzle.php

<?php

require __DIR__ . "/vendor/autoload.php";

$payload = json_encode([
    "title" => "Updated title"
]);

$headers = [
    "Content-type" => "application/json; charset=UTF-8"
];

$client = new GuzzleHttp\Client();

$response = $client->patch("https://jsonplaceholder.typicode.com/albums/1", [
    "headers" => $headers,
    "body" => $payload
]);

var_dump($response->getStatusCode());

var_dump($response->getHeader("Content-type"));

var_dump((string) $response->getBody());

4-sdks.php

<?php

$api_key = "your api key here";

$data = [
    'name' => 'Bob',
    'email' => 'bob@example.com'
];

/*
$ch = curl_init();

curl_setopt_array($ch, [
    CURLOPT_URL => 'https://api.stripe.com/v1/customers',
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_POSTFIELDS => http_build_query($data),
    CURLOPT_USERPWD => $api_key
]);

$data = curl_exec($ch);

curl_close($ch);

var_dump($data);
*/

require __DIR__ . "/vendor/autoload.php";

$stripe = new \Stripe\StripeClient($api_key);

$customer = $stripe->customers->create($data);

echo $customer;
