Check HTTP status codes, handle errors, and parse API payloads.

Check HTTP Status Code

Always check the HTTP status code before processing the response body.

<?php
$statusCode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
if ($statusCode !== 200) {
    throw new RuntimeException("API error: HTTP $statusCode");
}

Parse JSON Response

Decode the JSON body and handle parse errors.

<?php
$body = curl_exec($ch);
$data = json_decode($body, true, 512, JSON_THROW_ON_ERROR);
// $data is now a PHP array
