# Zend_Mime_Part

## Introduction

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.

## Instantiation

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:

    public $type = Zend_Mime::TYPE_OCTETSTREAM;
    public $encoding = Zend_Mime::ENCODING_8BIT;
    public $id;
    public $disposition;
    public $filename;
    public $description;
    public $charset;
    public $boundary;
    public $location;
    public $language;

## Methods for rendering the message part to a string

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.
