I think the term is "quoted word." It's sort of confusing.

With regular expression, of course.

function quoted_word_callback($m) {
switch($m[2]) {
case 'Q': case 'q': return quoted_printable_decode($m[3]);
case 'B': case 'b': return base64_decode($m[3]);
}
}

echo preg_replace_callback('/=\?(.*)\?([BQ])\?(.*)\?=/U',
'quoted_word_callback', $s);
