How to uniquely identify a computer?
php
Solution
Well, you won't be able to do this from only the HTTP request, but you do have at your disposal the following techniques:
- Remote Address
- Cookies/Session
- User Agent
- Client-side Web Technologies (e.g. Java or Flash or Silverlight object)
Basically, you can use the concepts of Evercookie to identifiy a client. That being said, why not just use a login system?
Problem
Is there any way to 'grab' some personalized ID, INFO, NAME, NUMBER, DATA, etc.? Anything just to differentiate and recognize two or more PC on the same IP: something like the Computer name of the user besides `$_SESSION`? None of these work: ``` $hostname = gethostbyaddr($_SERVER['REMOTE_ADDR']); php_uname('n'); php_uname(); ```
