html Output escaped, line breaks converted to <br>, appropriate for browser output
error_log Output to error log as configured in php.ini By default PHPMailer will use echo if run from a cli or cli-server SAPI, html otherwise. Alternatively, you can provide a callable expecting two params: a message string and the debug level:

$mail->Debugoutput = function($str, $level) {echo "debug level $level; message: $str";};

Alternatively, you can pass in an instance of a PSR-3 compatible logger, though only debug level output is used:

$mail->Debugoutput = new myPsr3Logger;

    public
        string
    $MessageID

If empty, a unique id will be generated. You can set your own, but it must be in the format "id@domain", as defined in RFC5322 section 3.6.4 or it will be ignored.

$Password

SMTP password.


    public
        string

$Sendmail

The path to the sendmail program.


    public
        string
    $Sendmail
     = '/usr/sbin/sendmail'

Which validator to use by default when validating email addresses.


    public
    static    string|callable

$WordWrap

Word-wrap the message body to this number of chars.


    public
        int
    $WordWrap

This can include images, sounds, and just about any other document type. If your filename doesn't contain an extension, be sure to set the $type to an appropriate MIME type.

Parameters

$string : string: The attachment binary data
$cid : string: Content ID of the attachment; Use this to reference the content when using an embedded image in HTML
$name : string = '': A filename for the attachment. If this contains an extension, PHPMailer will attempt to set a MIME type for the attachment. For example 'file.jpg' would get an 'image/jpeg' MIME type.

Create a message body from an HTML string.


    public
                    msgHTML(string $message[, string $basedir = '' ][, bool|callable $advanced = false ]) : 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) Converts data-uri images into embedded attachments. If you don't want to apply these transformations to your HTML, just set Body and AltBody directly.

Parameters

$message : string: HTML message string
$basedir : string = '': Absolute path to a base directory to prepend to relative paths to images
$advanced : bool|callable = false: Whether to use the internal HTML to text converter or your own custom converter

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)
Conversion to punycode is impossible (e.g. required PHP functions are not available) or fails for any reason (e.g. domain contains characters not allowed in an IDN).

string —

The encoded address in ASCII form

set()

Set or reset instance properties.


    public
                    set(string $name[, mixed $value = '' ]) : bool

You should avoid this function - it's more verbose, less efficient, more error-prone and harder to debug than setting properties directly. Usage Example: $mail->set('SMTPSecure', static::ENCRYPTION_STARTTLS); is the same as: $mail->SMTPSecure = static::ENCRYPTION_STARTTLS;.

Parameters

Return values

bool

Set the boundaries to use for delimiting MIME parts.

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.

addOrEnqueueAnAddress()
