How to get PC name

[patejl]

Hi, I would like to ask you if it is possible to check by PHP PC name somethig like GetHostByName. I can't validate users by IP because of their IP address is everyday different.

Regards
P.

as far as i'm aware, PHP can't get your pc's name. gethostbyname() (http://php.net/gethostbyname) return the resolved ip of a webserver. the name is a different thing altogether.

i don't even think the computer name is transmitted... but you might have some luck with something like javascript or java

You should make the users login. Checking anything else isn't really safe... if you (for what ever reason need it) get the servers name you can use $_ENV["COMPUTERNAME"].

Computer names are not unique to the computer, and no guarentee that it is truly the same person at the computer, nor is the IP address a valid way to ensure security. Dynamic IP addresses (56k) change with each reconnect.

The best way would be as marek suggested: a login. A nice tutorial can be found at http://biorust.com/index.php?page=tutorial_detail&tutid=115.
