[PHP-WINDOWS] checkdnsrr on WIN NT and IIS From: Andy Warwick (mail.list <email protected>)
Date: 06/24/00

Having a few problems with the checkdnsrr command under Windows NT and IIS.

The following code

    <?php
        if (checkdnsrr('creed.co.uk','ANY')) {echo "foo";}
        if (gethostbyname('creed.co.uk')) {echo "bar";}
    ?>

only gives the result "bar"

Any variation I try of checkdnsrr doesn't seem to work.

I'm trying to use the command to validate email addresses in forms, but even
though I can get the host name, it refused to believe their is a dns entry?

Doing a normal NS lookup shows the domain in question has got MX records.

    <nslookup:creed.co.uk/*/158.152.1.58>

    Non-authoritative answer:
    creed.co.uk NS 12954 ns1.netnames.net 212.53.64.60
    creed.co.uk NS 12954 ns2.netnames.net 212.53.77.28
    creed.co.uk MX 21556 10 relay1.netnames.net
    creed.co.uk MX 21556 20 relay2.netnames.net
    creed.co.uk SOA 21589 ns1.netnames.net
                                            hostmaster.netnames.net
                                            Serial 1
                                            Refresh 10800 (3 hours)
                                            Retry 1800 (30 minutes)
                                            Expire 3600000 (41 days)
                                            Minimum TTL 21600 (6 hours)

    Authority:
    creed.co.uk NS 12954 ns1.netnames.net
    creed.co.uk NS 12954 ns2.netnames.net
    NSLookup normal completion.

Any pointers as to where I'm going wrong or workarounds if its a WIN bug?

Regards
