/**

* +----------------------------- IMPORTANT ------------------------------+
|
||
* | Usage of this class compared to native php extensions such as |
|
||
* | mailparse or imap, is slow and may be feature deficient. If available|
|
||
* | you are STRONGLY recommended to use the php extensions. |
|

|
||
*
|
||
* Mime Decoding class
|
||
*
|
||
* This class will parse a raw mime email and return
|
||
* the structure. Returned structure is similar to
|
||
* that returned by imap_fetchstructure().
|
||
*
|
||
* USAGE: (assume $input is your raw email)
|
||
*
|
||
* $decode = new Mail_mimeDecode($input, "\r\n");
|
||
* $structure = $decode->decode();
|
||
* print_r($structure);
|
||
*
|
||
* Or statically:
|
||
*
|
||
* $params['input'] = $input;
|
||
* $structure = Mail_mimeDecode::decode($params);
|
||
* print_r($structure);
|
||
*
|
||
* TODO:
|
||
* o Implement multipart/appledouble
|
||
* o UTF8: ???
|
||
|
||
> 4. We have also found a solution for decoding the UTF-8
|
||
> headers. Therefore I made the following function:
|
||
>
|
||
> function decode_utf8($txt) {
|
||
> $trans=array("<22>‘"=>"õ","ű"=>"û","Ő"=>"<22>•","Ű"
|
||
=>"<22>›");
|
||
> $txt=strtr($txt,$trans);
|
||
> return(utf8_decode($txt));
|
||
> }
|
||
>
|
||
> And I have inserted the following line to the class:
|
||
>
|
||
> if (strtolower($charset)=="utf-8") $text=decode_utf8($text);
|
||
>
|
||
> ... before the following one in the "_decodeHeader" function:
|
||
>
|
||
> $input = str_replace($encoded, $text, $input);
|
||
>
|
||
> This way from now on it can easily decode the UTF-8 headers too.
