Class: PHPMailer  - X-Ref

PHPMailer - PHP email creation and transport class.

__construct($exceptions = null)   X-Ref
Constructor.

param: bool $exceptions Should we throw external exceptions?

__destruct()   X-Ref
Destructor.


mailPassthru($to, $subject, $body, $header, $params)   X-Ref
Call mail() in a safe_mode-aware fashion.
Also, unless sendmail_path points to sendmail (or something that
claims to be sendmail), don't pass params (not a perfect fix,
but it will do).

param: string      $to      To
param: string      $subject Subject
param: string      $body    Message Body
param: string      $header  Additional Header(s)
param: string|null $params  Params
return: bool

edebug($str)   X-Ref
Output debugging info via a user-defined method.
Only generates output if debug output is enabled.

param: string $str

isHTML($isHtml = true)   X-Ref
Sets message type to HTML or plain.

param: bool $isHtml True for HTML mode

isSMTP()   X-Ref
Send messages using SMTP.


isMail()   X-Ref
Send messages using PHP's mail() function.


isSendmail()   X-Ref
Send messages using $Sendmail.


isQmail()   X-Ref
Send messages using qmail.


addAddress($address, $name = '')   X-Ref
Add a "To" address.

param: string $address The email address to send to
param: string $name
return: bool true on success, false if address already used or invalid in some way

addCC($address, $name = '')   X-Ref
Add a "CC" address.

param: string $address The email address to send to
param: string $name
return: bool true on success, false if address already used or invalid in some way

addBCC($address, $name = '')   X-Ref
Add a "BCC" address.

param: string $address The email address to send to
param: string $name
return: bool true on success, false if address already used or invalid in some way

addReplyTo($address, $name = '')   X-Ref
Add a "Reply-To" address.

param: string $address The email address to reply to
param: string $name
return: bool true on success, false if address already used or invalid in some way

addOrEnqueueAnAddress($kind, $address, $name)   X-Ref
Add an address to one of the recipient arrays or to the ReplyTo array. Because PHPMailer
can't validate addresses with an IDN without knowing the PHPMailer::$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.

param: string $kind    One of 'to', 'cc', 'bcc', or 'ReplyTo'
param: string $address The email address to send, resp. to reply to
param: string $name
return: bool true on success, false if address already used or invalid in some way

addAnAddress($kind, $address, $name = '')   X-Ref
Add an address to one of the recipient arrays or to the ReplyTo array.
Addresses that have been added already return false, but do not throw exceptions.

param: string $kind    One of 'to', 'cc', 'bcc', or 'ReplyTo'
param: string $address The email address to send, resp. to reply to
param: string $name
return: bool true on success, false if address already used or invalid in some way

parseAddresses($addrstr, $useimap = true, $charset = self::CHARSET_ISO88591)   X-Ref
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.

param: string $addrstr The address list string
param: bool   $useimap Whether to use the IMAP extension to parse the list
return: array

setFrom($address, $name = '', $auto = true)   X-Ref
Set the From and FromName properties.

param: string $address
param: string $name
param: bool   $auto    Whether to also set the Sender address, defaults to true
return: bool

getLastMessageID()   X-Ref
Return the Message-ID header of the last email.
Technically this is the value from the last time the headers were created,
but it's also the message ID of the last sent message except in
pathological cases.

return: string

validateAddress($address, $patternselect = null)   X-Ref
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:

```php
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.

param: string          $address       The email address to check
param: string|callable $patternselect Which pattern to use
return: bool

idnSupported()   X-Ref
Tells whether IDNs (Internationalized Domain Names) are supported or not. This requires the
`intl` and `mbstring` PHP extensions.

return: bool `true` if required functions for IDN support are present

punyencodeAddress($address)   X-Ref
Converts IDN in given email address to its ASCII form, also known as punycode, if possible.
Important: Address must be passed in same encoding as currently set in PHPMailer::$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).

param: string $address The email address to convert
return: string The encoded address in ASCII form

send()   X-Ref
Create a message and send it.
Uses the sending method specified by $Mailer.

return: bool false on error - See the ErrorInfo property for details of the error

return: bool

param: string $string The string to be validated
return: bool

isPermittedPath($path)   X-Ref
Check whether a file path is of a permitted type.
Used to reject URLs and phar files from functions that access local file paths,
such as addAttachment.

param: string $path A relative or absolute path to a file

Provide an instance to use for SMTP operations.

return: SMTP

smtpSend($header, $body)   X-Ref
Send mail via SMTP.

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.

addEmbeddedImage($path,$cid,$name = '',$encoding = self::ENCODING_BASE64,$type = '',$disposition = 'inline')   X-Ref
Add an embedded (inline) attachment from a file.

param: string|null $value Header value

getCustomHeaders()   X-Ref
Returns all custom headers.

return: array

msgHTML($message, $basedir = '', $advanced = false)   X-Ref
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. <img src="/images/a.png"> 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.

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

html2text($html, $advanced = false)   X-Ref
Convert an HTML string into plain text.
This is used by msgHTML().
Note - older versions of this function used a bundled advanced converter
which was removed for license reasons in #232.
Example usage:

```php
//Use default conversion
$plain = $mail->html2text($html);
//Use your own custom converter
$plain = $mail->html2text($html, function($html) {
$converter = new MyHtml2text($html);
return $converter->get_text();
});

param: int|string $options Either a PATHINFO_* constant,
return: string|array

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

param: string $name  The property name to set

return: bool
