Accessing file directly in URL

[Levius]

Good day,

 

I created a file inside the prestashop installation. I have placed it inside the modules folder inside one of the module. When I tried accessing the file via the URL, it only outputs a white page. Does this has anything to do with .htaccess?

 

The url looks like this:
http://localhost/cosmetigate/modules/my_module/this_file.php

 

Thanks.
