如何從 PHP 向另一個 PHP 頁面發出 POST 請求？

Making a POST Request from PHP to Another PHP Page

In a PHP script, there may be instances where you need to send data to another PHP page. This can be achieved through a POST request. Here's how to accomplish it:

cURL Method

One method to make a POST request is using cURL. Whether as an extension or an external process, cURL provides a convenient way to handle POST requests.

<code class="php">// URL for the POST request
$url = 'http://foo.com/script.php';

// POST data
$fields = ['field1' => $field1, 'field2' => $field2];

// Build URL-encoded data
$postvars = http_build_query($fields);

// Initialize cURL connection
$ch = curl_init();

// Set URL, POST details, and POST data
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, count($fields));
curl_setopt($ch, CURLOPT_POSTFIELDS, $postvars);

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

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

Zend Framework

Another option is to utilize the Zend Framework's Zend_Http class. This library provides a robust HTTP client without the need for extensions.

Guzzle

For a more modern approach, consider Guzzle. This library offers an HTTP client that can operate with or without the cURL extension, providing flexibility and performance optimizations.
