(PHP ActiveX) DNS Query NS Records
Shows how to perform a DNS query to retrieve NS records.
Note: This example requires Chilkat v9.5.0.96 or later.
<?php
// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.Dns')
$dns = new COM("Chilkat.Dns");
// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.JsonObject')
$json = new COM("Chilkat.JsonObject");
$json->EmitCompact = 0;
$success = $dns->Query('NS','x.com',$json);
if ($success == 0) {
print $dns->LastErrorText . "\n";
exit;
}
print $json->emit() . "\n";
// Sample response.
// Parsing code below..
// {
// "answer": {
// "ns": [
// {
// "name": "x.com",
// "ttl": 86400,
// "domain": "alexia.ns.cloudflare.com"
// },
// {
// "name": "x.com",
// "ttl": 86400,
// "domain": "tosana.ns.cloudflare.com"
// }
// ]
// }
// }

$i = 0;
$count_i = $json->SizeOfArray('answer.ns');
while ($i < $count_i) {
$json->I = $i;
$name = $json->stringOf('answer.ns[i].name');
$ttl = $json->IntOf('answer.ns[i].ttl');
$domain = $json->stringOf('answer.ns[i].domain');
$i = $i + 1;
}
