Fatal error: Uncaught Error #49

I'm trying to obfuscate a small PHP file, I've tried to obfuscate the file with demo version too, same error happend. error: Fatal error: Uncaught Error: Class 'NwCfO' not found in C:\laragon\www\bings.php:8 Stack trace: #0 {main} thrown in C:\laragon\www\bings.php on line 8 here's the original PHP file:

header('Content-type: text/html; charset=UTF-8');
require_once 'bing.php';
$search = new bing_api("help");
$search->setDork('خرید گوشی');
$search->setCount(50);
// number of results on each page
$search->setSubLinks(TRUE);
// returns sublinks of the results if available

$search->search();
// start the search & extract the data
$descs = $search->getDescs(); // return the results ( title & link )
foreach($descs as $desc){
    echo $desc . '<br/>';
}
?>

here's the obfuscated file :

you obfuscate a file that makes reference to a non obfuscated one ( bing_api ...) try with :

$conf->obfuscate_class_name             = false;
$conf->obfuscate_method_name            = false;

or use $conf->t_ignore_classes and $conf->t_ignore_methods with classes and methods that you don't want to obfuscate!
