Translating IMAP body based on their encoding

Question

From the manual, I know that there are 6 different transfer encoding in IMAP.

At this point, I've created this basic function:

function translate_imap_body($body, $encoding) {
    switch($encoding) {
        case 0: return $body;break;
        case 1: return $body;break;
        case 2: return $body;break;
        case 3: return base64_decode($body);break;
        case 4: return quoted_printable_decode($body);break;
        case 5: return $body;break;
    }
}

My question is, how do I translate 8bit, binary, and other encoding back to human readable message form? Or, maybe someone has better functions to handle this?

Answer 1

To translate your 8 bit binary to human readable, try this:
