cURL と PHP を使用して JSON データを取得および解析するにはどうすればよいですか?

// Initiate cURL
$ch = curl_init();

// Set cURL options
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); // Return the response instead of printing it
curl_setopt($ch, CURLOPT_URL, $url); // Set the URL to retrieve the jSON from

// Execute the request and get the response
$result = curl_exec($ch);

// Close the cURL session
curl_close($ch);

// Parse the jSON response
$data = json_decode($result, true); // Decode the response as an associative array

$title = $data['threads']['38752']['title'];
$userId = $data['threads']['38752']['user_id'];
$username = $data['threads']['38752']['username'];
$postDate = $data['threads']['38752']['post_date'];
$sticky = $data['threads']['38752']['sticky'];
$discussionState = $data['threads']['38752']['discussion_state'];
$discussionOpen = $data['threads']['38752']['discussion_open'];
$message = $data['threads']['38752']['content']['content']['226167']['message'];

// Access the "count" element of the outer array
$count = $array['count'];

// Access the "thread_id" element of the first inner array (thread with id 13)
$threadId = $array['threads'][13]['thread_id'];
