如何通过PHP从URL获取.tld？
E.g。 www.domain.com/site,PHP应该发布：tld是：.com。
答案 0 :(得分：14)
使用parse_url()函数获取网址的主机部分然后按.展开并获取数组的最后一个元素
以下示例：
$url = 'http://www.example.com/site';
echo end(explode(".", parse_url($url, PHP_URL_HOST))); // echos "com"
在此之前，最好检查$ url是否是filter_var的实际网址，例如
修改
$url = 'http://' . $_SERVER['SERVER_NAME'];
echo end(explode(".", parse_url($url, PHP_URL_HOST)));
// echos "com"
答案 1 :(得分：8)
如果你想从字符串www.domain.com/site中提取主机，那么使用parse_url（）是可以接受的解决方案。
但是如果你想要提取域或其部分，你需要使用Public Suffix List的包。是的，您可以使用字符串函数arround parse_url（），但它会产生两个级别TLD的错误结果。
我建议TLDExtract进行域解析，这里是显示diff的示例代码：
$extract = new LayerShifter\TLDExtract\Extract();
# For 'http://www.domain.com/site'
$url = 'http://www.domain.com/site';
parse_url($url, PHP_URL_HOST); // will return www.domain.com
end(explode(".", parse_url($url, PHP_URL_HOST))); // will return com
$result = $extract->parse($url);
$result->getFullHost(); // will return 'www.domain.com'
$result->getRegistrableDomain(); // will return 'domain.com'
$result->getSuffix(); // will return 'com'
# For 'http://www.domain.co.uk/site'
$url = 'http://www.domain.co.uk/site';
parse_url($url, PHP_URL_HOST); // will return 'www.domain.co.uk'
end(explode(".", parse_url($url, PHP_URL_HOST))); // will return uk, not co.uk
$result = $extract->parse($url);
$result->getFullHost(); // will return 'www.domain.co.uk'
$result->getRegistrableDomain(); // will return 'domain.co.uk'
$result->getSuffix(); // will return 'co.uk'
答案 2 :(得分：3)
例如，接受的答案不适用于.co.uk。如果您的网址都具有相同的子域或根本没有子域，您可以执行以下操作。
$urls = array(
'http://domain.com/site/blah/',
'http://www.domain.com/site/blah/',
'http://www.domain.audio/site?hithere=1',
'http://www.domain.co.uk/site?somehing=%2babc',
);
$subdomain = 'www.';
foreach($urls as $url){
$host = parse_url($url, PHP_URL_HOST);
$host = str_ireplace($subdomain,'',$host);
$tld = strstr($host, '.');
echo "$tld | ";
}
输出： .com | .com | .audio | .co.uk |
答案 3 :(得分：0)
您可以使用preg_match。 http://php.net/manual/en/function.preg-match.php你应该专注于第三个例子。只需根据您的需求进行调整。

答案 5 :(得分：0)
简短回答
$extension = pathinfo($_SERVER['SERVER_NAME'], PATHINFO_EXTENSION);
容易！
答案 6 :(得分：0)
如果您不关心带点的LTD（例如“ co.uk”），并且由于触发了通知而不喜欢已经提到的explode + end解决方案，则可以执行此操作。
array_reverse((explode('.', $url)))[0];
答案 7 :(得分：0)
正如Rid Iculous所说的那样，parse_url（）方法不适用于.co.uk或.org.au等双重后缀。
这是一个PHP脚本，用于提取几乎可用的TLD。解决几乎所有案件都是有用的。也就是说，随着TLD随时间变化，使用TLDExtract是一种更可靠的方法。

Utopia Domains库（https://github.com/utopia-php/domains）将基于Mozilla公共后缀列表（https://publicsuffix.org）返回域TLD和公共后缀，它可以用作当前已归档TLDExtract程序包的替代。 / p>
您可以使用'parse_url'函数从URL获取主机名，然后使用Utopia Domains解析器获取正确的TLD：
<?php
require_once './vendor/autoload.php';
use Utopia\Domains\Domain;
$url = 'http://demo.example.co.uk/site';
$domain = new Domain(parse_url($url, PHP_URL_HOST)); // demo.example.co.uk
var_dump($domain->get()); // demo.example.co.uk
var_dump($domain->getTLD()); // uk
var_dump($domain->getSuffix()); // co.uk
var_dump($domain->getName()); // example
var_dump($domain->getSub()); // demo
var_dump($domain->isKnown()); // true
var_dump($domain->isICANN()); // true
var_dump($domain->isPrivate()); // false
var_dump($domain->isTest()); // false
