# Domains

## Get domain

To retrieve a specific domain, you will need the domain’s id, not its domain name:

    $domain = $service->domain('{domainId}');

If you are having trouble remembering or accessing the domain ID, you can do a domain list search for your domain and then access its ID.

## List domains

These calls provide a list of all DNS domains manageable by a given account. The resulting list is flat, and does not break the domains down hierarchically by subdomain. All representative domains are included in the list, even if a domain is conceptually a subdomain of another domain in the list.

    $domains = $service->domainList();

    # Return detailed information for each domain
    $domains = $service->domainList(true);

### Filter parameters

You can filter the search by using the `name` parameter in a key/value array supplied as a method argument. For example, to retrieve domains named `foo.com`, along with any subdomains like `bar.foo.com`:

    $hoolaDomains = $service->domainList(array(
        'name' => 'foo.com'
    ));

Filter criteria may consist of:

- Any letter (A-Za-z)
- Numbers (0-9)
- Hyphen (“-”)
- 1 to 63 characters

Filter criteria should not include any of the following characters:

> ‘ + , | ! ” £ $ % & / ( ) = ? ^ * ç ° § ; : _ > ] [ @ à, é, ò

### Finding a domain ID

Once you have a list of domains, to retrieve a domain’s ID:

    foreach ($domains as $domain) {
        $id = $domain->id;
    }

## List domain changes

This call shows all changes to the specified domain since the specified date/time. To list all available changes for a domain for the current day:

    $changes = $domain->changes();

For more granular control, you can manually define the `since` parameter like so:

    $since = date('c', strtotime('last week'));
    $changes = $domain->changes($since);

Once you have a set of changes, you can iterate over them like so:

    foreach ($changes->changes as $change) {
        printf("Domain: %s\nAction: %s\nTarget: %s", $change->domain, $change->action, $change->targetType);

        foreach ($change->changeDetails as $detail) {
            printf("Details: %s was changed from %s to %s", $detail->field, $detail->oldValue, $detail->newValue);
        }
    }

## Create domain

The first thing you will need to do is instantiate a new object and set the primary `A` record for the DNS domain, like so:

    // get empty object
    $domain = $service->domain();

    // add A record
    $aRecord = $domain->record(array(
        'type' => 'A',
        'name' => 'example.com',
        'data' => '192.0.2.17',
        'ttl'  => 3600
    ));

    $domain->addRecord($aRecord);

You also have the option of adding more types of DNS records such as `CNAME`, `MX` and `NS` records. This step is completely optional and depends on your requirements:

    // add CNAME record
    $cRecord = $domain->record(array(
        'type' => 'CNAME',
        'name' => 'www.example.com',
        'data' => 'example.com',
        'ttl'  => 3600
    ));
    $domain->addRecord($cRecord);

    // add MX record
    $mxRecord = $domain->record(array(
        'type' => 'MX',
        'data' => 'mail.example.com',
        'name' => 'example.com',
        'ttl'  => 3600,
        'priority' => 5
    ));
    $domain->addRecord($mxRecord);

    // add NS record
    $nsRecord = $domain->record(array(
        'type' => 'NS',
        'data' => 'dns1.stabletransit.com',
        'name' => 'example.com',
        'ttl'  => 5400
    ));
    $domain->addRecord($nsRecord);

You can also add sub-domains to your new DNS domain. Again, this is completely optional:

    $subdomain = $domain->subdomain(array(
        'emailAddress' => 'foo@example.com',
        'name'         => 'dev.example.com',
        'comment'      => 'Dev portal'
    ));
    $domain->addSubdomain($subdomain);

Once you’ve finished configuring how your DNS domain will work, you’re ready to specify the essential details and send it to the API for creation:

    $domain->create(array(
        'emailAddress' => 'webmaster@example.com',
        'ttl'          => 3600,
        'name'         => 'example.com',
        'comment'      => 'Optional comment'
    ));

## Clone domain

This call will duplicate an existing domain under a new name. By default, all records and, optionally, subdomains are duplicated as well.

The method signature you will need to use is:

`cloneDomain`($newDomainName[, $subdomains[, $comments[, $email[, $records]]]])

  Clone a domain

  Parameters: | $newDomainName (string) – The name of the new domain entry $subdomains (bool) – Set to `true` to clone all the subdomains for this domain $comments (bool) – Set to `true` to replace occurrences of the reference domain name with the new domain name in comments on the cloned (new) domain. $email (bool) – Set to `true` to replace occurrences of the reference domain name with the new domain name in data fields (of records) on the cloned (new) domain. Does not affect NS records. $records (bool) – Set to `true` to replace occurrences of the reference domain name with the new domain name in data fields (of records) on the cloned (new) domain. Does not affect NS records.

For example:

    $asyncResponse = $domain->cloneDomain('new-name.com', true, false, true, false);

## Export domain

This call provides access to the BIND (Berkeley Internet Name Domain) 9 for the requested domain. This call is for a single domain only, and as such, does not traverse up or down the domain hierarchy for details:

    $asyncResponse = $domain->export();

    $body = $asyncResponse->waitFor('COMPLETED');
    echo $body['contents'];

## Import domain

This operation will create a new DNS domain according to a BIND (Berkeley Internet Name Domain) 9 formatted value.

In order for the BIND value to be considered valid, it needs to adhere to the following rules:

- Each record starts on a new line and on the first column. If a record will not fit on one line, use the BIND_9 line continuation convention where you put a left parenthesis and continue the one record on the next line and put a right parenthesis when the record ends. For example:

  > example2.net. 3600 IN SOA dns1.stabletransit.com. (sample@rackspace.com. 1308874739 3600 3600 3600 3600)

- The attribute values of a record must be separated by a single blank or tab. No other white space characters.

- If there are any NS records, the data field should not be `dns1.stabletransit.com` or `dns2.stabletransit.com`. They will result in “duplicate record” errors.

For example:

    $bind9Data = <<<EOT

    example.net. 3600 IN SOA dns1.stabletransit.com. sample@rackspace.com. 1308874739 3600 3600 3600 3600
    example.net. 86400 IN A 110.11.12.16
    example.net. 3600 IN MX 5 mail2.example.net.
    www.example.net. 5400 IN CNAME example.net.

    EOT;

    $asyncResponse = $service->import($bind9Data);

## Modify domain

Only the TTL, email address and comment attributes of a domain can be modified. Records cannot be added, modified, or removed through this API operation - you will need to use the add records, modify records or remove records operations respectively.

    $domain->update(array(
        'ttl'          => ($domain->ttl + 100),
        'emailAddress' => 'new_dev@foo.com'
    ));

## Delete domain

    $domain->delete();
