一个接收邮件乱码的问题

[cxxlp]

接收邮件主题是乱码，如下图



=?Big5?Q?brown6065ab_=B7Q=A6V=A7A=B1=C0=C2=CB=B3o=A5=F3_eBay_=AA=AB=AB~?=

请问如何，显示正常字符，显示正常字符应该是：

brown6065ab 想向你推薦這件 eBay 物品

这样写

$s = '=?Big5?Q?brown6065ab_=B7Q=A6V=A7A=B1=C0=C2=CB=B3o=A5=F3_eBay_=AA=AB=AB~?=';

$t = explode('?', $s);
$func = strtoupper($t[2]) == 'B' ? 'base64_decode' : 'quoted_printable_decode';
echo iconv($t[1], 'gbk', $func($t[3]));

我博客里面有篇文章，写了如何解决这个问题
主要的代码是下面这个函数

   /**
     * decode the subject of chinese
     *
     * @param string $subject
     * @return sting
     */
    public function subjectDecode($subject) {
        $separator = '=?GB2312';
        $encode = strstr($subject,$separator);
        if($encode) {
            $explodeArr = explode($separator,$subject);
            $length = count($explodeArr);
            $subjectArr = array();
            for($i = 0;$i < $length/2;$i++) {
                $subjectArr[$i][] = $explodeArr[$i*2];
                if(@$explodeArr[$i*2 + 1]) {
                    $subjectArr[$i][] = $explodeArr[$i*2 + 1];
                }
            }
            foreach ($subjectArr as $arr) {
                $subSubject = implode($separator,$arr);
                if(count($arr) == 1) {
                    $subSubject = $separator.$subSubject;
                }
                $begin = strpos($subSubject ,"=?") ;
                $end = strpos($subSubject , "?=") ;
                $beginStr = '';
                $endStr = '';
                if ($end >0) {
                    if ($begin > 0) {
                        $beginStr = substr($subSubject,0,$begin) ;
                    }
                    if ((strlen($subSubject) - $end)> 2) {
                        $endStr = substr($subSubject,$end + 2 , strlen($subSubject)-$end-2) ;
                    }
                    $str = substr($subSubject,0, $end - strlen($subSubject) );
                    $pos = strrpos($str,"?") ;
                    $str = substr($str,$pos + 1 ,strlen($str)-$pos);
                    $subSubject = $beginStr . imap_base64($str) . $endStr ;
                    $subSubjectArr[] = mb_convert_encoding($subSubject,'utf-8','gbk');
                }
            }
            $subject = implode('',$subSubjectArr);
        }
        return $subject ;
    }
