Question

I am selling PHP script online at 35$ for a individual user

Is there any way to identify whether , my script is hosted by more than one user ..

Should i use any logic in my script to find his identity?

Is there an easy way to find the pirator

Please help me.
(sorry for grammatical mistakes)

Answer 1

For example, somewhere in your script:

<?php
file_get_contents('http://yourserver.com/tranck_script_users.php?site='.url_encode($_SERVER['HTTP_HOST']));
?>

This way you will see which hosts use your script. Of course, anyone can remove this line from your script, there is no 100% way to know for sure.
