Consider to usehttps://github.com/jeremykendall/php-domain-parser as maintained alternative.
TLDExtract
accurately separates the gTLD or ccTLD (generic or country code top-level domain) from the registered domain and subdomains of a URL, e.g. domain parser. For example, say you want just the 'google' part of 'http://www.google.com'.
Everybody gets this wrong. Splitting on the '.' and taking the last 2 elements goes a long way only if you're thinking of simple e.g. .com domains. Think parsinghttp://forums.bbc.co.uk for example: the naive splitting method above will give you 'co' as the domain and 'uk' as the TLD, instead of 'bbc' and 'co.uk' respectively.
TLDExtract
on the other hand knows what all gTLDs and ccTLDs look like by looking up the currently living ones according tothe Public Suffix List. So, given a URL, it knows its subdomain from its domain, and its domain from its country code.
$result =tld_extract('http://forums.news.cnn.com/');var_dump($result);object(LayerShifter\TLDExtract\Result)#34 (3) { ["subdomain":"LayerShifter\TLDExtract\Result":private]=> string(11)"forums.news" ["hostname":"LayerShifter\TLDExtract\Result":private]=> string(3)"cnn" ["suffix":"LayerShifter\TLDExtract\Result":private]=> string(3)"com"}
Result
implements ArrayAccess interface, so you simple can access to its result.
var_dump($result['subdomain']);string(11)"forums.news"var_dump($result['hostname']);string(3)"cnn"var_dump($result['suffix']);string(3)"com"
Also you can simply convert result to JSON.
var_dump($result->toJson());string(54)"{"subdomain":"forums.news","hostname":"cnn","suffix":"com"}"
This package is compliant withPSR-1,PSR-2,PSR-4. If you notice compliance oversights, please send a patch via pull request.
No.TLDExtract
uses database fromTLDDatabase that generated from Public Suffix List and updated regularly. It does not make any HTTP requests to parse or validate a domain.
The following versions of PHP are supported.
- PHP 5.5
- PHP 5.6
- PHP 7.0
- PHP 7.1
- PHP 7.2
- PHP 7.3
- HHVM
Via Composer
$ composer require layershifter/tld-extract
ClassLayerShifter\TLDExtract\Result
has some usable methods:
$extract =newLayerShifter\TLDExtract\Extract();# For domain 'shop.github.com'$result =$extract->parse('shop.github.com');$result->getFullHost();// will return (string) 'shop.github.com'$result->getRegistrableDomain();// will return (string) 'github.com'$result->isValidDomain();// will return (bool) true$result->isIp();// will return (bool) false# For IP '192.168.0.1'$result =$extract->parse('192.168.0.1');$result->getFullHost();// will return (string) '192.168.0.1'$result->getRegistrableDomain();// will return null$result->isValidDomain();// will return (bool) false$result->isIp();// will return (bool) true
By default package is using database fromTLDDatabase package, but you can override this behaviour simply:
newLayerShifter\TLDExtract\Extract(__DIR__ .'/cache/mydatabase.php');
For more details and how keep database updatedTLDDatabase.
By default after parse you will receive object ofLayerShifter\TLDExtract\Result
class, but sometime you need own methods or additional functionality.
You can create own class that implementsLayerShifter\TLDExtract\ResultInterface
and use it as parse result.
class CustomResultimplementsLayerShifter\TLDExtract\ResultInterface {}newLayerShifter\TLDExtract\Extract(null, CustomResult::class);
Package has three modes of parsing:
- allow ICANN suffixes (domains are those delegated by ICANN or part of the IANA root zone database);
- allow private domains (domains are amendments submitted to Public Suffix List by the domain holder, as an expression of how they operate their domain security policy);
- allow custom (domains that are not in list, but can be usable, for example: example, mycompany, etc).
For keeping compatibility with Public Suffix List ideas package runs in all these modes by default, but you can easily change this behavior:
useLayerShifter\TLDExtract\Extract;newExtract(null,null, Extract::MODE_ALLOW_ICANN);newExtract(null,null, Extract::MODE_ALLOW_PRIVATE);newExtract(null,null, Extract::MODE_ALLOW_NOT_EXISTING_SUFFIXES);newExtract(null,null, Extract::MODE_ALLOW_ICANN | Extract::MODE_ALLOW_PRIVATE);
