Email Address Encoder – Till

Plugin encodes email addresses in content.

Can be used to encode email addresses in templates as follows:

If the content is a PHP string, run it through the eae_encode_emails() function:

$text = eae_encode_emails($text);

To encode a single email address, use the eae_encode_str() function:

echo eae_encode_str('name@domain.com');
