$ch = curl_init('http://www.example.com');
curl_setopt($ch, CURLOPT_POSTFIELDS, $request_body);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "DELETE");
$response = curl_exec($ch);
var_dump($response);
?>
