Script not giving any ouput

[philharmonie]

I followed the readme, installed the script using composer, modified lines 13-17 like:

define('FHP_BANK_URL', 'https://hbci-pintan-he.s-hbci.de/PinTanServlet');
define('FHP_BANK_PORT', 443); 
define('FHP_BANK_CODE', '50650023');
define('FHP_ONLINE_BANKING_USERNAME', 'online banking user name');
define('FHP_ONLINE_BANKING_PIN', 'online banking password');  

and ran the script. It loads very long and gave no output.
I'm running the script on my local host with active internet connection.
