使用RegExp从Whois中提取信息

Question

如何从Whois查找的结果中提取多个段？

我得到一个数组，它的结果来自Whois查找(来自foreach循环(。

例如，如果我想要从WHOIS数据库的"domain…."行到">>>Last update"的所有内容：-行。我该怎么做？

Whois使用exec命令执行：

foreach ($query as $domain) {               
$scanUrl = 'whois '.$domain->url;
exec($scanUrl, $output);             
}

Whois工作没有问题，我可以用preg_rep:获得创建、过期和注册器

$domainCreated  = preg_grep('/created/', $output);
$domainExpires  = preg_grep('/expires/', $output);
$domainRegistrar  = preg_grep('/registrar..........:/', $output);

但我需要从数组中获得多个片段，例如从域中。。。。行到>>WHOIS数据库的上次更新：-行。

所有Whois结果都在一个数组中。Whois的结果如下：

我试过这样的东西：

$domainRawScan = preg_grep('/bdomainb.*b>>> Last update of WHOIS database:b/', $output);

但我对使用RegExp非常陌生，发现语法相当混乱。如有任何帮助，我们将不胜感激。

Answer 1

一种方法是获取exec命令返回的$output数组，并将其返回为单个字符串：

$text = implode("n", $output)

然后使用preg_match_all获取所有关键字和值

preg_match_all('/^(.*?)\.*: (.+)/m', $text, $matches);

则$matches[1][n]将具有关键字n，而$matches[2][n]将具有值n。

Regex Demo

^             # Start of line in multiline mode
(             # Start of capture group 1
.*?        # Match 0 or more characters until ...
)             # End of capture group 1
.*           # Match 0 or more periods
:             # Match a colon followed by a space
(             # Start of capture group 2
.+         # Match 1 or more characters up to but not including a newline
)             # End of capture group 2

更新

每次通过循环，您将处理一个域和关键字/值对。你将如何处理这些取决于你自己。

foreach ($query as $domain) {
$scanUrl = 'whois '. $domain->url;
$output = []; // start with an empty array
exec($scanUrl, $output);
$text = implode("n", $output);
preg_match_all('/^(.*?)\.*: (.+)/m', $text, $matches);
$n = count($matches[1]); // number of keyword/value pairs
for ($i = 0; $i < $n; $i++) {
// display next keyword/value pair:
echo $matches[1][$i], "->", $matches[2][$i], "n";
}
}

更新2

与其将exec命令返回的行数组连接到一个字符串中并执行preg_match_all(这将为您提供一个匹配数组(，不如对exec命令的各个输出行执行单独的preg_match调用：

foreach ($query as $domain) {
$scanUrl = 'whois '. $domain->url;
$output = []; // start with an empty array
exec($scanUrl, $output);
foreach ($output as $line) {
if (preg_match('/^(.*?)\.*: (.+)/', $line, $matches)) {
echo $matches[1], "->", $matches[2], "n";
}
}    
}
