By design, most DNS servers won't let you do this because it's something of
a security risk.
However, for DNS servers that *will* let you do it, there isn't a built-in
function in PHP that will do what you want, but I imagine you can accomplish
it by interacting with a unix shell and using the nslookup command. I don't
know the code to do this, but am sure there are tons of examples around.
Once you get access to the shell, the commands you want are as follows:
shellprompt> nslookup
shellprompt> ls -t any domainname.com
where domainname.com is the domain you're looking for.
Again, note that 9 times out of 10, you're going to get a "Query Refused"
result since most DNS servers won't give you this information. You can get
an idea of your success rate by simply trying the above commands in your own
*nix shell for various domain names. Most/all of the big guys (yahoo, sun,
etc.) are blocked.
