wasn't the symfony's mail_to helper supposed to do the same?

see http://www.symfony-project.com/content/book/page/templating_link_helpers.html

Well, there are thousands of ways to encode an email address. This snippet is one, and mail_to is another (without javascript). And neither of those are very convincing, if you ask me...

Yes, it's true that mail_to helper does the same thing. The reason why I've posted this snippet is that I wasn't aware of mail_to() existance :)

My bad.

No, the mail_to helper does not do the same thing. It does not use javascript, whereas this snippet does. mail_to only "encodes" email addresses using xhtml codes.
