Hostname Grabbing

[xianaier]

Hi, I don't know if this is possible. But, I would like to know fi anyone has a php script which can grab a hostname of a person. A lot of my visitors have dynamic ip addresses. So according to what I have learned. When tehy restart, if I have blocked their ip. They will still have access because their ip address will be different. Does anyone have a script which will get he hostname, which is permanent. Or a script which will solve the problem

Thanks

I guess no script available for this. All you have to do is look in to the php manual. You need to use the super global $_server.

$_ SERVER['REMOTE_HOST']

'REMOTE_HOST'
The host name from which the user is viewing the current page. The reverse dns lookup is based on the REMOTE_ADDR of the user.

But remember, they are not permanent either, they might be changed.
