Mail::parseRecipients

(

$recipients

)

Take a set of recipients and parse them, returning an array of bare addresses (forward paths) that can be passed to sendmail or an smtp server with the rcpt to: command.

Parameters

mixed

Either a comma-seperated list of recipients (RFC822 compliant), or an array of recipients, each RFC822 valid.

Returns

mixed An array of forward paths (bare addresses) or a PEAR_Error object if the address list could not be parsed. private

Mail::prepareHeaders

(

$headers

)

Take an array of mail headers and return a string containing text usable in sending a message.

Parameters

array

$headers

The array of headers to prepare, in an associative array, where the array key is the header name (ie, 'Subject'), and the array value is the header value (ie, 'test'). The header produced from those values would be 'Subject: test'.

Returns

mixed Returns false if it encounters a bad address, otherwise returns an array containing two elements: Any From: address found in the headers, and the plain text version of the headers. private

Mail::send	(		$recipients,
			$headers,
			$body
	)

Implements Mail::send() function using php's built-in mail() command.

Parameters

mixed	$recipients	Either a comma-seperated list of recipients (RFC822 compliant), or an array of recipients, each RFC822 valid. This may contain recipients not specified in the headers, for Bcc:, resending messages, etc.
array	$headers	The array of headers to send with the mail, in an associative array, where the array key is the header name (ie, 'Subject'), and the array value is the header value (ie, 'test'). The header produced from those values would be 'Subject: test'.
string	$body	The full text of the message body, including any Mime parts, etc.

Returns

mixed Returns true on success, or a PEAR_Error containing a descriptive error message on failure.

public

Deprecated:

use Mail_mail::send instead
