$curl_1 = curl_init();
curl_setopt($curl_1, CURLOPT_POSTFIELDS, $post_data_1);
echo "OK\n";

// exactly the same as above + added a reference to 'file' element
$post_data_2 = [ 'file' => new CURLFile('file.txt') ];
$ref = & $post_data_2['file']; // ***
$curl_2 = curl_init();
curl_setopt($curl_2, CURLOPT_POSTFIELDS, $post_data_2);
