You want to write a DNS server in php?

[morfeas]

Not exacly but yes is it possible to write
a dns server in php ?

Even if it were possible using sockets [us.php.net] I wouldn't recommend doing it. For anything like that I would personally use C/C++.

[morfeas]

thanks for your answer but if i write a c / c++
program a c++ variable have to be passed to
a php variable
is that possible?

There are Program Execuiton Functions [us.php.net]. You should be able to grab the output from a executable into your PHP app.

Well, yeah. But there are a lot of gotchas you'd have to worry about. Perhaps if you just stated the problem you are trying to solve, we could come up with a better solution.
