Why am I getting such random results when checking DNS?
- by animuson
The code is as follows:
$domain = "fosajfjdkgdajfhsd.com";
$check1 = checkdnsrr($domain, "MX");
$check2 = checkdnsrr($domain, "A");
$check3 = (checkdnsrr($domain, "MX") || checkdnsrr($domain, "A"));
$check4 = !(checkdnsrr($domain, "MX") || checkdnsrr($domain, "A"));
die("{$check1} - {$check2} - {$check3} - {$check4}");
However when I check the output to see what it's returning, I get this:
- 1 - 1 -
The domain obviously wouldn't exist, so I don't understand why checking the A record is return true and checking the MX result doesn't give me anything at all. I don't understand what's going wrong here.
