How can I send POST data using fopen() or cURL?

---

Here's an example that uses the PHP curl to send POST data:

<?

$ch = curl_init();

$data = array('var1' => 'Foo', 'var2' => 'Bar');

curl_setopt($ch, CURLOPT_URL, 'http://localhost/');
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);

curl_exec($ch);
?>

You can find more information on curl in the PHP documentation.
