How to perform an Zone Transfer (AXFR):

require_once("Net/DNS.php");
$res = new Net_DNS_Resolver();
$res->debug = 1;
$answer = $res->axfr("example.com");
echo "<BR><HR><BR>";
print_r($answer);

This example will query the name server and output the following:

;; axfr_start(example.com, IN)
;; query(example.com, AXFR, IN)
;; axfr_start(208.79.80.18:53)
;; sending 29 bytes
;; read_tcp: expecting 2 bytes
;; read_tcp: received 2 bytes
;; read_tcp: expecting 29 bytes
;; read_tcp: received 29 bytes
;; received 29bytes
