Add a "To" address.

addAddress(string $address, string $name = '') : boolean

Parameters

$address

Add an attachment from a path on the filesystem.

addAttachment(string $path, string $name = '', string $encoding = 'base64', string $type = '', string $disposition = 'attachment') : boolean

Never use a user-supplied path to a file! Returns false if the file could not be found or read. Explicitly does not support passing URLs; PHPMailer is not an HTTP client. If you need to do that, fetch the resource yourself and pass it in via a local file or string.

Parameters

$path

string

Path to the attachment.

$name

string

Overrides the attachment name.

$encoding

string

File encoding (see $Encoding).

$type

string

File extension (MIME) type.

string

Disposition to use

Exceptions

`\phpmailerException`

Returns

boolean

addBCC(string $address, string $name = '') : boolean

note	: This function works with the SMTP mailer on win32, not with the "mail" mailer.

Parameters

$address

string

The email address to send to

$name

string

Returns

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

Add a "CC" address.

addCC(string $address, string $name = '') : boolean

static

Parameters

Create a message body from an HTML string.

msgHTML(string $message, string $basedir = '', boolean|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) If you don't want to apply these transformations to your HTML, just set Body and AltBody directly.

access	public

Parameters

$message

string

HTML message string

$basedir

string

Absolute path to a base directory to prepend to relative paths to images

$advanced

booleancallable

Whether to use the internal HTML to text converter or your own custom converter @see PHPMailer::html2text()

Returns

Parse and validate a string containing one or more RFC822-style comma-separated email addresses of the form "display name <address>" into an array of name/address pairs.

Returns

Actually send a message.

preSend() : boolean

Exceptions

`\phpmailerException`

Returns

boolean

Converts IDN in given email address to its ASCII form, also known as punycode, if possible.

punyencodeAddress(string $address) : string

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 has characters not allowed in an IDN)

Parameters

$address

string

The email address to convert

Returns

stringThe encoded address in ASCII form

Return an RFC 822 formatted date.

secureHeader(string $str) : string

access	public

Parameters

$str

string

Exceptions

`\phpmailerException`

Returns

booleanfalse on error - See the ErrorInfo property for details of the error.

Set or reset instance properties.

set(string $name, mixed $value = '') : boolean

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', 'tls'); is the same as: $mail->SMTPSecure = 'tls';

access	public
TODO	Should this not be using the __set() magic function?

Parameters

$name

string

The property name to set

$value

mixed

The value to set the property to

Returns

boolean

Set the From and FromName properties.

setFrom(string $address, string $name = '', boolean $auto = true) : boolean

Returns

boolean

Apply word wrapping to the message body.

setWordWrap() : void

Wraps the message body to the number of chars set in the WordWrap property. You should only do this to plain-text bodies as wrapping HTML tags may break them. This is called automatically by createBody(), so you don't need to call it yourself.

access	public

Set the public and private key files and password for S/MIME signing.

sign(string $cert_filename, string $key_filename, string $key_pass, string $extracerts_filename = '')

access	public

Parameters

$address

string

The email address to check

$patternselect

stringcallable

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.
