I'm making a sort of domain searcher.
Basically the user types in a text box the domain that the want to see is available or not.
The only thing I tried was this:
That didn't work
Does anybody know how to do this???
-thanks

Having a domain doesn't mean it would respond to a page request. I'd suggest using a WHOIS request.

ok well I don't really need a domain I just need to check if any address that the user types in exists.
Is that at all possible?

you might want to check out this
http://uk.php.net/manual/en/ref.curl.php
Also you would need your installation of php to be compiled with curl, use
phpinfo() to find out if it has been installed on your server.

cURL? What for? gethostbynamel() returns false if there is no "A" record and if you really want to be precise get the document status.

Nice function,
gethostbyname(). Honestly, I didn't know it existed (see, you learn something everyday here). But make sure to read the user comments, specifically about caching, as this might affect the performance of your checking.

not
gethostbyname()! I was recomending
gethostbynamel() which returns false on failure. Note the "L" at the end.
