Hi there,
My provider stopped the DNS service on the server that runs mySQL and
PHP. By result, the function GetHostByAddr() is useless. Can I tell PHP
to use another DNS server to lookup the IP-address?
No PHP uses whatever is configured on the system. PHP just does the
gethostbyaddr() call, and the system does the rest. One solution
could be to call an external program like host or something. host
can be told to use a specific nameserver, and does not depend on
system configuration.

Hmm, not a very satisfying answer. I don't know of any Linux program, that
I know it's not very satisfying, but on most Linux installations you have
the program called host. Try host ipaddress serveraddress. If you
have this, it is simple to call the program from PHP and use the output.
does what you suggest. Wouldn't it be handy to extend the function (or have
another one), so that it can use any DNS server, that is parsed to the
function?
Sorry, but I'm against adding all that extra code for a special case
like this. Personally I would say that if service provider blocked
DNS, then the provider is the problem. If provider wants to, he can
block all DNS lookups going out from the box. I'm cc-ing this to
php-dev.
