Consider to use https://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 parsing http://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 to the 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 with PSR-1, PSR-2, PSR-4. If you notice compliance oversights, please send a patch via pull request.
No. TLDExtract uses database from TLDDatabase 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-extractClass LayerShifter\TLDExtract\Result has some usable methods:
$extract = new LayerShifter\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) trueBy default package is using database from TLDDatabase package, but you can override this behaviour simply:
new LayerShifter\TLDExtract\Extract(__DIR__ . '/cache/mydatabase.php');For more details and how keep database updated TLDDatabase.
By default after parse you will receive object of LayerShifter\TLDExtract\Result class, but sometime you need own methods or additional functionality.
You can create own class that implements LayerShifter\TLDExtract\ResultInterface and use it as parse result.
class CustomResult implements LayerShifter\TLDExtract\ResultInterface {}
new LayerShifter\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:
use LayerShifter\TLDExtract\Extract;
new Extract(null, null, Extract::MODE_ALLOW_ICANN);
new Extract(null, null, Extract::MODE_ALLOW_PRIVATE);
new Extract(null, null, Extract::MODE_ALLOW_NOT_EXISTING_SUFFIXES);
new Extract(null, null, Extract::MODE_ALLOW_ICANN | Extract::MODE_ALLOW_PRIVATE);Please see CHANGELOG for more information what has changed recently.
