Description Description
Important: Address must be passed in same encoding as currently set in PHPMailer::$CharSet. This function silently returns unmodified address if:

- Conversion to punycode is impossible (e.g. required PHP functions are not available) or fails for any reason (e.g. domain has characters not allowed in an IDN)
Parameters Parameters
- $address
-
(Required) The email address to convert
Return Return
(string) The encoded address in ASCII form
