我想将一个 API 与我的一个网站集成，这是我的前辈给的任务。API 是关于搜索已经存在或不存在的域名。请在这个主题上帮助我，请给我一个我可以参考的例子。我的网站是 PHP 的。

[编辑 2]正如@Poe 在他的评论中提到的，gethostbyname可能是一个更好的解决方案，因为它适用于任何顶级域，因为它执行 DNS 查询而不是 whois 查询，而且实现起来也更简单，可能更快：
<?php
$ip = gethostbyname('example.com');
if (strstr($ip,"example.com")){
echo "No match for domain example.com<br />\n";
} else {
echo "Domain found. Query output: <br />\n".$ip;
}
?>
无论如何，可以注册一个域，但它不链接到任何计算机（例如，虽然它非常罕见，但您可能会得到 www.example.com 的解析，但不是 example.com）
[编辑]我之前没有发布此内容，因为我在连接到端口 43 上的 whois.internic.net 以执行 whois 查询时遇到了一些问题（以为他们已经永久关闭了该服务）。无论如何，这是我刚刚编写的基于fsockopen的解决方案，我认为它比我在使用他们的 CGI Web 脚本之前提供的解决方案要好得多，也更简单。希望它有所帮助（用法：myqueryscript.php?domain=domainiwanttocheck.com）：
<?php
$fp = fsockopen("199.7.58.74", 43, $errno, $errstr, 30);
if (!$fp) {
echo "$errstr ($errno)<br />\n";
} else {
$query = $_GET['domain']."\r\n";
$answer= '';
fwrite($fp, $query);
while (!feof($fp)) {
$answer .= fgets($fp, 128)."<br />";
}
fclose($fp);
if (strstr($answer,"No match for")){
echo "No match for domain ".$_GET['domain']."<br />\n";
} else {
echo "Domain found. Query output: <br />\n".$answer;
}
}
?>
来自 internic 网站，这是实现 whois 查询的 html 代码：
<form method="get" action="http://reports.internic.net/cgi/whois" name="my_form">
<input type="text" size="30" name="whois_nic" maxlength="80">
<br>
<input type="radio" name="type" value="domain" checked>
Domain<font size="-1"> (ex. internic.net)
<br>
<input type="radio" name="type" value="registrar">
Registrar<font size="-1"> (ex. ABC Registrar, Inc.)
<br>
<input type="radio" name="type" value="nameserver">
Nameserver (ex. NS.EXAMPLE.COM or 192.16.0.192)<br>
<br>
<input type="submit" value="Submit">
</form>
这意味着您可以发送这样的 whois 查询：http ://reports.internic.net/cgi/whois?whois_nic=domainiwanttocheck.com&type=domain
您可以从脚本发送查询并将响应存储在 DOMDocument 对象中。查看：http ://www.php.net/manual/en/domdocument.loadhtml.php
如果您使用此方法查找域并且该域不存在，您将获得 string No match for domain。使用strpos在响应中查找此内容
如果域存在，您可以过滤响应以包含有关注册商等的信息。它将是<pre>响应的 html 标记的内容：

获取域名和tld
<?php
$host = 'https://compute-1.hyd.in.securedatacenter.host';
preg_match("/[^\.\/]+\.[^\.\/]+$/", $host, $matches);
$data = explode('.',$matches['0']);
//print_r($data);
echo 'Your domain name is :- '.$data['0'].'<br>';
echo 'Your tld is :- '.$data['1'];
