sorry, I have no experience at all with PHP and never coded..
I am looking to host a website where I will be serving pdf documents to my clients.. but when clients clicks on download -- i need to modify pdf and put unique id at few places so that they cannot distribute my documents.
also i need to write this unique id and ip address to a text file on server
how can i accomplish this?
i am looking at php for a solution since basic webhosting allows php progrmming bvy default .. but for anything like asp/coldfusion/jsp/java etc i have to pay extra ..
please help if these things can be accomplished with php programming..
