Re: email character decoding

found another special case; malformed HTML (CRLF *inside* html tags).. the following update to getPart() fixes it : function getPart($connection, $messageNumber, $partNumber, $encoding) { setlocale(LC_CTYPE, 'nl_NL.utf8'); $header = imap_fetchheader($connection, $messageNumber); //return $header; $data = imap_fetchbody($connection, $messageNumber, $partNumber); if ($data == '') return $data; //return $encoding; switch($encoding) { case 0: //if (mb_detect_encoding($data, 'UTF-8', true)==='UTF-8') { $d = quoted_printable_decode($data); if ( strpos($d, '<body')!==false || strpos($d, '<table')!==false ) $d = str_replace ("\r\n", "", $d); //return $d; $f = fopen ('temp/data.bin', 'w'); if ($f!==false) { fwrite ($f, $d); fclose ($f); $xec = 'chardet "'.dirname(__FILE__).'/temp/data.bin"'; exec ($xec, $output, $result); preg_match_all('/: (.*) with/',$output[0],$chardet); //return json_encode($output); $chardetResult = $chardet[1][0]; if ($chardetResult=='utf-8') return $d; $xec = 'iconv -f '.$chardetResult.' -t UTF-8 "'.dirname(__FILE__).'/temp/data.bin" > "'.dirname(__FILE__).'/temp/data.out"'; exec ($xec, $output, $result); return file_get_contents(dirname(__FILE__).'/temp/data.out'); } else { echo 'Could not open temp/data.bin for detection and conversion of character set encoding :(<br/>Please check directory permissions on "'.dirname(__FILE__).'/temp"'; }; /* } else { return $data; // 7BIT }*/ case 1: return imap_8bit($data); // 8BIT case 2: return $data; // BINARY case 3: return imap_base64($data); // BASE64 case 4: if ( is_base64($data)){ $d = base64_decode($data);
