APNIC data objects
A PHP library to read, write, and validate APNIC RPSL objects.
Reading Objects
The utility class WhoisParser can read the output retrieved from the whois command and turn it into RPSL objects.
use Dormilich\APNIC\Utilities\WhoisParser;
$reader = new WhoisParser;
// of course you can use any CLI processor you like
$whois = `whois '192.186.2.0 - 192.186.2.8' -h whois.apnic.net`; # using GNU whois here
try {
if ($net = $reader->parse($whois)) {
// do something with the Inetnum object ...
}
}
catch (Exception $e) {
// ... or show any problems you got while parsing
echo $e;
}If you are certain which object to expect, you can feed it to the parser. This will always get you an object back.
use Dormilich\APNIC\Utilities\WhoisParser;
use Dormilich\APNIC\RPSL\Inetnum;
$reader = new WhoisParser;
$whois = `whois '192.186.2.0 - 192.186.2.8' -h whois.apnic.net -rxB`;
try {
// unlike the first example, $net will always be an RPSL object
$net = $reader->parse($whois, new Inetnum(null));
if (!$net->isValid()) {
// something is left out
}
// do something with the Inetnum object ...
}
catch (Exception $e) {
echo $e;
}If you want to read all RPSL objects from the output, that’s also possible. The only downside is that you don’t know beforehand what’s all inside …
use Dormilich\APNIC\Utilities\WhoisParser;
$reader = new WhoisParser;
$whois = `whois '192.186.2.0 - 192.186.2.8' -h whois.apnic.net -rxB`;
try {
$data = $reader->parseAll($whois);
$net = $data['192.186.2.0 - 192.186.2.8'];
$admin1 = $data[ $net['admin-c'][0] ];
// ...
}
catch (Exception $e) {
echo $e;
}Working with Objects
The RPSL objects allow to conveniently edit RPSL data.
use Dormilich\APNIC\RPSL\Person;
$person = new Person;
// set a value to an attribute
$person['person'] = 'John Doe';
$person->set('source', 'APNIC');
// add values to a multiple attribute
$person
->add('address', 'infinity drive 1')
->add('address', 'anytown')
;
// get a value from an attribute
echo $person['person']; // John Doe
echo $person->get('source'); // APNIC
$address = $person->get('address'); // ['infinity drive 1', 'anytown']
// delete values
unset($person['source']);
var_dump( $person->get('source') ); // NULLBut you’re not limited to primitive values, attributes that accept handles allow the appropriate object as input. And for the most common attributes, these even get validated.
// you can even pass RPSL objects to appropriate attributes
$maint = ... // get that object from whois
$obj['mnt-by'] = $maint;
// common attributes that contain references validate any passed RPSL object
// e.g. this throws an exception since tech contacts can only be Person or Role handles
$obj->add('tech-c', $maint);Templates … for that the RPSL objects and their attributes are iterable.
Writing Objects
'Writing' may be a bit of an exaggeration. Essentially, printing an object creates its textual representation that you can use in an email update.
use Dormilich\APNIC\Utilities\WhoisParser;
$reader = new WhoisParser;
$whois = `whois JD12-AP -h whois.apnic.net -rB`;
try {
if ($john = $reader->parse($whois)) {
$john
->add('phone', '+1 234 567 8901')
->add('e-mail', 'john.doe@example.com')
;
$body = $john . 'password: ' . $my_apnic_password;
// please use a proper email client!
mail('auto-dbm@apnic.net', $john->getHandle(), $body, ...);
}
}
catch (Exception $e) {
echo $e;
}
