README

The aim of this project is to create abstract object representations of DNS records in PHP. The project consists of various classes representing DNS objects (such as Zone, ResourceRecord, and various RData types), a parser to convert BIND style text files to the PHP objects, and builders to create aesthetically pleasing BIND records.

echo AlignedBuilder::build($zone);

Output

; A RECORDS
sub.domain   IN A    192.168.1.42; This is a local ip.

; AAAA RECORDS
ipv6.domain  IN AAAA ::1; This is an IPv6 domain.

; MX RECORDS
@            IN MX   10 mail-gw1.example.net.
@            IN MX   20 mail-gw2.example.net.
@            IN MX   30 mail-gw3.example.net.

; LOC RECORDS
canberra     IN LOC  (
                     35 18 27.000 S ; LATITUDE

                     ); This is Canberra

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

...
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.

Parsing BIND Records

BIND Records can be parsed into PHP objects using Badcow\DNS\Parser\Parser

$file = file_get_contents('/path/to/example.com.txt');
$zone = Badcow\DNS\Parser\Parser::parse('example.com.', $file); //Badcow Zone Object

Simple as that.
