我需要一个正则表达式来匹配这个：

Second reply. #2

Met vriendelijke groet,
{sender name}

{company details}

并在找到时停止匹配：

On 25-02-15 14:38, {email name} wrote:

或者当找到这个时：

##- Please type your reply above this line -##

我自己对正则表达式的了解不够，所以我希望有人能帮助我解决这个问题。此文本是通过电子邮件收到的，所以对我来说最重要的是匹配此 ##- Please type your reply above this line -##.

Answer 1

请检查：

$re = "/^(.*?)(?=On\s+\d{2}\-\d+\-\d+|\#{2}\-.*?\-\#{2})/s"; 
$str = "YOUR_INPUT_STRING"; 

preg_match($re, $str, $matches);

见Demo here。

如果##-之前的>不匹配，使用^:

$re = "/^(.*?)(?=On\s+\d{2}\-\d+\-\d+|\^\s*\#{2}\-.*?\-\#{2})/s";

Answer 2

试试这个：

preg_match('#^(.*)\#\#- Please type your reply#s', $string, $matches);

您的结果应该在 $matches[1] 中找到。
