On a side note after reading what you said a second time (since I still don't quite understand what you mean) if this 'password of the script' you are referring to is the database password, simply put all of the database details (username, password, etc.) into a separate file and upload it outside of the document root directory, then include it in your file(s) that need it. Web browsers can not view files outside of the document root, however your server can still link to/process them.
