This class represents a single part of a MIME message. It contains the actual content of the message part plus information about its encoding, content type and original filename. It provides a method for generating a string from the stored data. Zend_Mime_Part objects can be added to Zend_Mime_Message to assemble a complete multipart message. Zend_Mime_Part is instantiated with a string that represents the content of the new part. The type is assumed to be OCTET-STREAM, encoding is 8Bit. After instantiating a Zend_Mime_Part, meta information can be set by accessing its attributes directly: getContent() returns the encoded content of the MimePart as a string using the encoding specified in the attribute $encoding. Valid values are Zend_Mime::ENCODING_* Characterset conversions are not performed. getHeaders() returns the Mime-Headers for the MimePart as generated from the information in the publicly accessible attributes. The attributes of the object need to be set correctly before this method is called. $charset has to be set to the actual charset of the content if it is a text type (Text or HTML). $id may be set to identify a content-id for inline images in a HTML mail. $filename contains the name the file will get when downloading it. $disposition defines if the file should be treated as an attachment or if it is used inside the (HTML-) mail (inline). $description is only used for informational purposes. $boundary defines string as boundary. $location can be used as resource URI that has relation to the content. $language defines languages in the content.
