Add an address to one of the recipient arrays or to the ReplyTo array. Because PHPMailer can't validate addresses with an IDN without knowing the PHPMailer::$CharSet (that can still be modified after calling this function), addition of such addresses is delayed until send(). Addresses that have been added already return false, but do not throw exceptions.

Parameters

`$kind`	One of 'to', 'cc', 'bcc', or 'ReplyTo'
`$address`	The email address to send, resp. to reply to

Returns

true on success, false if address already used or invalid in some way

validateAddress(string $address, string|callable $patternselect = null): boolean

Check that a string looks like an email address.

Parameters

$address

The email address to check

$patternselect

A selector for the validation pattern to use :

auto Pick best pattern automatically;
pcre8 Use the squiloople.com pattern, requires PCRE > 8.0, PHP >= 5.3.2, 5.2.14;
pcre Use old PCRE implementation;
php Use PHP built-in FILTER_VALIDATE_EMAIL;
html5 Use the pattern given by the HTML5 spec for 'email' type form input elements.
noregex Don't use a regex: super fast, really dumb. Alternatively you may pass in a callable to inject your own validator, for example: PHPMailer::validateAddress('user@example.com', function($address) { return (strpos($address, '@') !== false); }); You can also set the PHPMailer::$validator static to a callable, allowing built-in methods to use your validator.

Converts IDN in given email address to its ASCII form, also known as punycode, if possible. Important: Address must be passed in same encoding as currently set in PHPMailer::$CharSet. This function silently returns unmodified address if:

No conversion is necessary (i.e. domain name is not an IDN, or is already in ASCII form)

The encoded address in ASCII form

Create a message body from an HTML string. Automatically inlines images and creates a plain-text version by converting the HTML, overwriting any existing values in Body and AltBody. Do not source $message content from user input! $basedir is prepended when handling relative URLs, e.g. and must not be empty will look for an image file in $basedir/images/a.png and convert it to inline. If you don't provide a $basedir, relative paths will be left untouched (and thus probably break in email) If you don't want to apply these transformations to your HTML, just set Body and AltBody directly.

Parameters

`$message`	HTML message string
`$basedir`	Absolute path to a base directory to prepend to relative paths to images
`$advanced`	Whether to use the internal HTML to text converter or your own custom converter @see PHPMailer::html2text()

$message The transformed message Body
