我有一个脚本提供一些 IP 地址的信息。

我想从文本中提取国家。

在以下文本中，国家行是"Country: US"

我想显示：US仅

正文是：

[Querying whois.arin.net]
[whois.arin.net]

使用 preg_match 您可以执行以下操作：

if (preg_match('/^Country:\s*([A-Z]{2,3)$/m', $str, $match)) {
    echo $match[1];
}

如果它只是您需要的正则表达式 - 试试这个 - 国家 ID 将在第一组

Country:\s*([A-Z]{2})
  • Country:- 匹配文字
  • \s*- 匹配任意数量的空格、制表符等。
  • ([A-Z]{2})- 匹配并捕获任何字母（大写）两次

preg_match_all如果您需要此模式的所有出现，请使用

有一个用于处理 whois 数据的phpwhois库。它会让你得到一个数组的响应。

使用 preg_match 提取

preg_match("/Country:(.*)\"/siU", $str, $match);
echo trim($match[1]);

$regex = "/country:[\ \t\r\n\f][A-Z]+\s/";

$txt = "descr: NCC#200X44704917
country: FR
admin-c: ACPSA223-RIPE
tech-c: TCWQQP8-RIPE";

preg_match($regex, $txt, $result);

print_r($result);

------------------------------------------------
数组 ( [0] => 国家: FR )
