A nice way to decode strings is to use the mb_list_encodings(), but I had two problems with it: sometimes, the charset is uppercase in the header an lowercase in mb_list_encodings() and sometimes, the charset is not in the mb_list_encodings() list.<?phpfunction upperListEncode() { $encodes=mb_list_encodings(); foreach ($encodes as $encode) $tencode[]=strtoupper($encode); return $tencode; }function decode($string) { $tabChaine=imap_mime_header_decode($string); $texte=''; for ($i=0; $i<count($tabChaine); $i++) { switch (strtoupper($tabChaine[$i]->charset)) { case 'UTF-8': $texte.= $tabChaine[$i]->text; break; case 'DEFAULT': $texte.= $tabChaine[$i]->text; break; default: if (in_array(strtoupper($tabChaine[$i]->charset),upperListEncode())) {$texte.= mb_convert_encoding($tabChaine[$i]->text,'UTF-8',$tabChaine[$i]->charset);} else { $ret = iconv($tabChaine[$i]->charset, "UTF-8", $tabChaine[$i]->text); if (!$ret) $texte.=$tabChaine[$i]->text; else $texte.=$ret; } break; } } return $texte; }?>
