Example usage

require_once __DIR__ . '/vendor/autoload.php';

use Badcow\DNS\Zone;

The above is an example of the AlignedBuilder which creates records that are much more aesthetically pleasing. You can also use the flat ZoneBuilder, whose output looks like below:

...
$zoneBuilder = new ZoneBuilder();

echo $zoneBuilder->build($zone);

$ORIGIN example.com.
$TTL 3600
canberra  IN LOC 35 18 27.000 S 149 7 27.840 E 500.00m 20.12m 200.30m 300.10m; This is Canberra
@  IN MX 20 mail-gw2.example.net.
@  IN SOA example.com. post.example.com. 2014110501 3600 14400 604800 3600
@  IN NS ns1.nameserver.com.
@  IN MX 30 mail-gw3.example.net.
sub.domain  IN A 192.168.1.42; This is a local ip.
ipv6.domain  IN AAAA ::1; This is an IPv6 domain.
@  IN NS ns2.nameserver.com.
@  IN MX 10 mail-gw1.example.net.

Running the tests

Simply use phpunit to run the tests. You can run additional tests if you have BIND installed. Add the environment variable to phpunit.xml:

Or add it at run-time:

CHECKZONE_PATH="/path/to/named-checkzone" phpunit .
