How to read content of pass.pkpass file and send in text/xml restfull webservice response

Question

I impleted https://github.com/tschoffelen/php-pkpass to generate pkpass.

I integrated in backed restfull api which send response in text/xml content type.

I am trying to read .pkpass file in backed and send in api response as below that could be decoded by ios app and use this pkpass.

but using file-get-content we are not geting valid content that could be sent as string. this works fine if we use this to dowload file from web browser.

Is there anything that I am missing to read content of .pkpass file.

public function create($output = false)
    {
        $paths = $this->getTempPaths();
        // Creates and saves the json manifest
        if(!($manifest = $this->createManifest())) {
            $this->clean();

            return false;
        }

        // Create signature
        if($this->createSignature($manifest) == false) {
            $this->clean();

            return false;
        }

        if($this->createZip($manifest) == false) {
            $this->clean();

            return false;
        }

        // Check if pass is created and valid
        if(!file_exists($paths['pkpass']) || filesize($paths['pkpass']) < 1) {
            $this->sError = 'Error while creating pass.pkpass. Check your ZIP extension.';
            $this->clean();

            return false;
        }

        // Get contents of generated file
        $file = file_get_contents($paths['pkpass']);
        $size = filesize($paths['pkpass']);
        $name = basename($paths['pkpass']);

        // Cleanup
        //$this->clean();

        // Output pass
        if($output == true) {
            $fileName = $this->getName() ? $this->getName() : $name;
            if(!strstr($fileName, '.')) {
                $fileName .= '.pkpass';
            }
            header('Content-Description: File Transfer');
            header('Content-Type: application/vnd.apple.pkpass');
            header('Content-Disposition: attachment; filename="' . $fileName . '"');
            header('Content-Transfer-Encoding: binary');
            header('Connection: Keep-Alive');
            header('Expires: 0');
            header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
            header('Last-Modified: ' . gmdate('D, d M Y H:i:s T'));
            header('Pragma: public');
            header('Content-Length: ' . $size);
            @ob_end_flush();
            set_time_limit(0);
            echo $file;

            return true;
        }
        return $file;
    }

method call

$pk_pass =  $pass->create('false');

$xml = '<?xml version="1.0" encoding="UTF-8"?>';
$xml .= '<root>';
$xml .= '<pass>'.$pk_pass.'</pass>';
$xml .= '</root>';

Response I get as below

<?xml version="1.0" encoding="UTF-8"?>

Answer 1

@praveen I had done this before few days ago but not with xml. I just tell you provide url intend of .pkpass content. like http://example.com/pass/xx where xx is id/serial of that pass. which is process in php and prepare pass with appropriate content. when someone hit this url fresh generate .pkpass.
