Function and features of the module

E-mail addresses must not be in plain text on web pages, so that advertising mail senders cannot „collect“ e-mail addresses. To disguise email addresses (and also other data, such as phone numbers), the following PHP function can be used.

Integration of the module

In the TUCAL editor, this information is entered in the „Seiteneinstellungen (PHP)“ (page settings) text field:

require_once('php/mail.inc');
page settings in the editor
