<div class="refsect1title">Description</div>
<p>This function is used to make a MIME part that can be used with the
<span class="computeroutput">mime_body()</span> function.</p>
</div>
<div class="refsect1">
<div class="refsect1title">Parameters</div>
<div class="refsect2">
<span class="refsect2title">content_type – </span>
This parameter is used to specify the media type and subtype of data
in the body of a message and to fully specify the native representation of
such data. This header embodies much of the power of MIME. The IETF can
add new official content types. Additionally, private content-type values can
be defined by anyone. Such private content types have values of
"x-something" or "X-something", where "something" can take on
any value.</div>
<div class="refsect2">
<span class="refsect2title">content_disposition – </span>
This parameter provides information about how to present a
body part. When a body part is to be treated as an attached file, the
Content-Disposition header should include a file name parameter.</div>
<div class="refsect2">
<span class="refsect2title">transfer_encoding – </span>
The encoding method to use, such as base64.</div>
<div class="refsect2">
<span class="refsect2title">data – </span>
The content of the message.</div>
</div>
<div class="refsect1">
<div class="refsect1title">Return Types</div>
<p>The function returns a MIME part for use with the <span class="computeroutput">mime_body()</span> function.</p>
