PHPMailer\PHPMailer\PHPMailer::addAttachment	(		$path,
			$name = '',
			$encoding = self::ENCODING_BASE64,

Add an attachment from a path on the filesystem.

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

string	$path	Path to the attachment
string	$name	Overrides the attachment name
string	$encoding	File encoding (see $Encoding)
string	$type	File extension (MIME) type
string	$disposition	Disposition to use

Exceptions

string	$cid	Content ID of the attachment; Use this to reference the content when using an embedded image in HTML
string	$name	Overrides the attachment name
string	$encoding	File encoding (see $Encoding)

addOrEnqueueAnAddress()

PHPMailer\PHPMailer\PHPMailer::addOrEnqueueAnAddress (   $kind,   $address,   $name  )

protected

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

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

Exceptions

Exception

Returns

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

msgHTML()

PHPMailer\PHPMailer\PHPMailer::msgHTML	(		$message,
			$basedir = '',
			$advanced = false
	)

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) 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

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

Returns

string $message The transformed message Body

Exceptions

Exception

parseAddresses()

static PHPMailer\PHPMailer\PHPMailer::parseAddresses (   $addrstr,   $useimap = true  )

static

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.

Uses the imap_rfc822_parse_adrlist function if the IMAP extension is available. Note that quotes in the name part are removed.

Returns

punyencodeAddress()

PHPMailer\PHPMailer\PHPMailer::punyencodeAddress

(

$address

)

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)
• 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).

Parameters

string

$address

The email address to convert

Returns

string The encoded address in ASCII form

validateAddress()

static PHPMailer\PHPMailer\PHPMailer::validateAddress (   $address,   $patternselect = null  )

static

Check that a string looks like an email address.

Validation patterns supported:

• auto Pick best pattern automatically;
• pcre8 Use the squiloople.com pattern, requires PCRE > 8.0;
• 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.

Parameters

string	$address	The email address to check
string | callable	$patternselect	Which pattern to use

Returns

bool
