使用正则表达式删除电子邮件地址后的结束段落标记

Question

I'm using

public function __construct()
{
    $this->EE =& get_instance();
    $regex = '/(\S+@\S+\.\S+)/';
    $replace = '<a href="mailto:$1">$1</a>';


    $this->return_data = preg_replace($regex, $replace, ee()->TMPL->tagdata);
}

to find plain text email address and changing them to mailto links, however, the wysiwyg editor is putting the ending paragraph tag right after the link so it's catching the ending tag and putting it in to the mailto link. I need my regex to exclude anything after the .com or .net or whatever. How would I do this?

Right now, it's returning mailto:[e-mail]

, I need to exlude any and all tags that come after the .com

Here is a part of the dump, This is what's outputted:

<br />
Preston Newbill<br />
Manager<br />
[e-mail]</p>

Answer 1

You could try changing your regular expression to the following:

/(\S+@\S+\.[^\<]+)/

This would stop capturing when it encounters the first < at the Top-level domain.

@ukliviu suggests a more restrictive approach that will have even fewer false positives than HTML tags.
