imap php乱码问题的解决办法：首先打开相应的PHP文件；然后添加iconv进行字符编码格式转换即可解决乱码问题，其语句如“iconv('gb2312','utf8',imap_base64($text));”。

php imap/pop3 接收邮件类，解决中文乱码
小弟目的想在嵌入式开发板上实现接收邮件，当然谷歌了一下，发现还是有很多实现方法的：php最简单，C socket实现效率最高（我是这么感觉），当然也少不了python实现（不过还没动手测试）等等。
今天先介绍一下php 接受邮件类，这个类最初是老外Mitul Koradia写的，感觉实现功能也很完整：
该类的主要方法如下：
class receiveMail{ ... function receiveMail($username,$password,$EmailAddress,$mailserver='localhost',$servertype='pop',$port='110',$ssl = false) //Constructure function getHeaders($mid) // Get Header info function getTotalMails() //Get Total Number off Unread Email In Mailbox function getUnreadMails() //Get Number of Unread Mail from Mailbox function searchUnreadMails() //Find Numbers of Unread Mail by imap_search Method function GetAttach($mid,$path) // Get Atteced File from Mail function getBody($mid) // Get Message Body function deleteMails($mid) // Delete That Mail function close_mailbox() //Close Mail Box不过有些瑕疵，我阅读后稍作修改，主要是邮件头没进行MIME解码，邮件中文内容乱码。
首先关于邮件头的解码过程，Mitul Koradia的处理方法如下：
function getHeaders($mid) // Get Header info{if(!$this->marubox)return false;$mail_header=imap_header($this->marubox,$mid);$sender=$mail_header->from[0];$sender_replyto=$mail_header->reply_to[0];if(strtolower($sender->mailbox)!='mailer-daemon' && strtolower($sender->mailbox)!='postmaster'){$mail_details=array('from'=>strtolower($sender->mailbox).'@'.$sender->host,'fromName'=>$sender->personal,'subject'=>$mail_header->subject,'to'=>$mail_header->toaddress);}return $mail_details;}但是返回结果是MIME编码字符，显然不行，于是添加了imap_mime_header_decode方法后就可以了。
function getHeaders($mid) // Get Header info{if(!$this->marubox)return false;$mail_header=imap_header($this->marubox,$mid);$sender=$mail_header->from[0];$sender_replyto=$mail_header->reply_to[0];if(strtolower($sender->mailbox)!='mailer-daemon' && strtolower($sender->mailbox)!='postmaster'){$mail_details=array('from'=>strtolower($sender->mailbox).'@'.$sender->host,'fromName'=>imap_mime_header_decode($sender->personal)[0]->text,'subject'=>imap_mime_header_decode($mail_header->subject)[0]->text,'to'=>imap_mime_header_decode($mail_header->toaddress)[0]->text);}return $mail_details;}最后关于邮件中文内容乱码的问题，老外肯定不会去考虑啦，其实也是比较简单，添加iconv进行字符编码格式转换即可：
function get_part($stream, $msg_number, $mime_type, $structure = false, $part_number = false) //Get Part Of Message Internal Private Use{ if(!$structure) { $structure = imap_fetchstructure($stream, $msg_number); } if($structure) { if($mime_type == $this->get_mime_type($structure)){ if(!$part_number) { $part_number = "1"; } $text = imap_fetchbody($stream, $msg_number, $part_number); if($structure->encoding == 3) { return iconv('gb2312','utf8',imap_base64($text)); } else if($structure->encoding == 4) { return iconv('gb2312','utf8',imap_qprint($text)); } else{ return iconv('gb2312','utf8',$text); } } if($structure->type == 1) /* multipart */ { while(list($index, $sub_structure) = each($structure->parts)){ if($part_number){ $prefix = $part_number . '.'; } $data = $this->get_part($stream, $msg_number, $mime_type, $sub_structure, $prefix . ($index + 1)); if($data){ return $data; } } } } return false; }初学PHP，感觉很多还不懂，希望能再接再厉
