Nested bodyparts?

I am trying to find the text part of a message. My code looks a bit like this:

if ($mime->Decode($parameters, $decoded))
{

foreach ($decoded[0]['Parts'] as $part)
{
if (strpos($part['Headers']['content-type:'], "text/plain") !== false)
{
$textbody = $part['Body'];
break;
}
}
}

This doesn't work when the text/plain is embedded within a multipart/alternative. Is there a recommended way to recurse through nested bodyparts?

When a message part contains other parts, there is an array entry with key name Parts that details the contained parts.

Anyway, the Analyze function can do that analysis for you. Is there any reason why you are not using the Analyze function?

Thanks for your reply.

Do you have sample code for use of Parts?

I use the Analyze function but not for getting bodyparts? I've looked at the doc at http://corporate.psionline.com/parser/mime_parser_class.html#9.2.4 and it's not clear to me how it would handle multipart/alternative (for example whether it would return an HTML or a text if both are present).

Analyze returns both parts as long as Decode returns all body parts, so you cannot use the SkipBody option.

I found it easier to use the Decode. Code here if anyone needs it.

function getTextBP($logh, $parts)
{
$textbody = '';

foreach ($parts as $part)
{
fwrite($logh , "Process bodypart\n");
fwrite($logh , "ctype " . $part['Headers']['content-type:'] . "\n");

if (strpos($part['Headers']['content-type:'], "multipart/alternative") !== false)
{
return(getTextBP($logh, $part['Parts']));
}
else if (strpos($part['Headers']['content-type:'], "text/plain") !== false)
{
fwrite($logh, "Got text/plain\n");
$textbody = $part['Body'];
break;
}
}

return($textbody);
}

$textbody = getTextBP($logh, $decoded['0']['Parts']);

Well, that is what the Analyze function does, except that it also returns the HTML body as the main body part according to the e-mail standards.
