cURL 및 Zend Framework를 사용하여 PHP에서 HTTP POST 요청을 구현하는 방법은 무엇입니까?

<code class="php">// $url: Target PHP page URL
// $fields: Associative array of POST fields (e.g., ['field1' => 'val1'])

$postvars = http_build_query($fields); // Encode fields

// Initialize cURL
$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, count($fields));
curl_setopt($ch, CURLOPT_POSTFIELDS, $postvars);

$result = curl_exec($ch); // Execute POST request

curl_close($ch); // Close connection</code>

<code class="php">use Zend\Http\Client;

// $url: Target PHP page URL
// $client: Zend_Http_Client object

$client->setParameterPost($fields);
$response = $client->post($url);

// Process response here</code>
