如何在WYSIWYG编辑器中使用方括号对文本进行后处理？

Question

I need to obfuscate email addresses before they are published on my users' sites, to prevent spambots from scraping them. However, some users like to use mailto links (against my advice, but they do what they will), and my obfuscation function breaks the mailtos. So I'd like to make it easy for site admins to slap obfuscation around some email addresses but not others.

I want to use syntax like this:

"Some text, some more text, an [emailaddress@example.com], and more text."

Which will output

"Some text, some more text, an emailaddress<span class='obfuscate' style='display:none;'>@</span>example.com, and more text."

Is there a standard way to get PHP to evaluate and process only the text in the square brackets? I've seen similar notation in Wordpress code, for example,

[contact-form-7] 

is typed in the WYSIWYG editor, and will be rendered as a fully formed contact form to the public. So how can I do that?

我使用了以下正则表达式：[[\\ w。] + @ [\\ w] +。[\\ w] +]查找括在方括号中的电子邮件地址，并将其替换为混淆后的字符串。
