Good e-mail link protection methods

Question

Can you guys post methods of e-mail link spam-protection (in php or javascript)?

Basically I want to put a "mailto" link on a web page, like

<a href="mailto:[email protected]">E-mail me</a>

but I don't want the spam bots to pick it up and then spam me with penis enlargement emails :)

So far, I found a javascript obfuscator here: http://www.jottings.com/obfuscator/ Not sure how effective it is though..

JavaScript Solution

With JavaScript you can do the following.

emailE = ('yourname@' + 'emailserver.com')
document.write('<A href="mailto:' + emailE + '">' + emailE + '</a>')

With this, Crawlers can no longer read your email from source code.

PHP solution

With php you can convert your email to unicode values

function converte($email) {
    $p = str_split(trim($email));
    $new_mail = '';
    foreach ($p as $val) {
        $new_mail .= '&#'.ord($val).';';
    }
    return $new_mail;
}

and on your page use the function like

<?php echo converte('[email protected]'); ?>

Source code output will be something like

mail.com
