Question

尝试查找REGEX以从PHP中的字符串中获取电子邮件标头中的列表取消订阅。

string是$ row ['emailHeader'];

当前代码：

preg_match_all('[Ll]ist-[Uu]nsubscribe:([^\r\n)', $row['emailHeader'], $matches);

这给了我零比赛。我正在寻找不区分大小写的'list-unsubscribe：'，直到下一个电子邮件标题开始为止。 list-unsubscribe通常后跟http://..或者http://...。无论哪种方式，我都可以从标题中提取这些内容后对它们进行排序，但我遇到了正则表达式的问题。

示例标题

理想情况下，我想要第二个列表 - 仅取消订阅，但我可以处理两者并进行搜索。

Answer 1

preg_match_all("#List-Unsubscribe:(.*)#i", $row['emailHeader'], $matches);

Answer 2

你必须使用： ^ - 开始行 $ - 结束 m - 多行匹配所有行

// join headers. It's possible headers to be split to 2 rows
$header = preg_replace("@\r\n\s+@", " ", $row['emailHeader']);

// i is for case insensitive, m is for multiline
preg_match_all('/^list\\-unsubscribe:(.*)$/mi', $headers, $matches);

正则表达式获取列表 - 取消订阅标题
