How to detect if laptop is being used

hi all
I m making a website in which my client requires to track if the user
of his site is using laptop or Desktop computer. How is it possible as
i have no idea .

Second question is we should be even able to track type of internet
service provider user of website is using for some security purpose
and if user changes his internet service provider then he should not
be allowed to access the site.

It's not possible at all. May I ask why your client demands something
like this?

Not really possible as well, at least not reliably. And same question as
above - why?

They might be using neither.

Determining what kind of computer a browser is running on is
impossible.

ISP tracking might be possible if you did a reverse lookup on the
$_SERVER ['REMOTE_ADDR'] field, but it wouldn't be reliable. And why
would you want to block a user if they come in from a different ISP
anyway? They could be on holiday or at work or any number of things.

Ask the user - drop a cookie with their answer - you can't enforce it
though.

There's no requirement for service providers to publish PTR addresses
- most don't. A whois lookup would be more apposite - but it's a
meaningless problem - so the solutions are meaningless too.

Is there some way --using, say, DOM or javascript-- to detect the current pixel width and/or height of a relatively sized table or of one of its columns or rows. I'm going to be writing javascript to adjust my page to the viewer's browser window dimensions and this would sure be great information to have. Thanks .... Dennis

I am trying to learn PHP and was reading the book by Laura Welling and Luke Thompson. Obviously, PHP is already installed on a server when hosted by an ISP already. Is there a way to just download PHP 5 onto my laptop as well as MYSQL and practice learning it with coding and scripts, etc.? I don't have another machine to install Apache or IIS. Thanks.
