发送MIME邮件~~其实我对他的格式一窍不通，是看着OUTLOOK中的源码写的_PHP教程

class mime_mail { var $boundary0="----=_NextPart_000_00EE_01C07425.958FDFE0";//三条分界，0是附件，2是HTML，1是要附加的图片 var $boundary1="----=_NextPart_001_00EF_01C07425.958FDFE0"; var $boundary2="----=_NextPart_002_00F0_01C07425.958FDFE0"; var $body; function get_mail_header()//邮件头 { return $this->mail_header="MIME-Version: 1.0 Content-Type: multipart/mixed; boundary="$this->boundary0" This is a multi-part message in MIME format. --$this->boundary0 Content-Type: multipart/related; boundary="$this->boundary1"; type="multipart/alternative" --$this->boundary1 Content-Type: multipart/alternative; boundary="$this->boundary2" "; } function str_row($str,$n)//把字符串分割成n行,OUTLOOK中好象必须把BASE64割成$n) { $new_str.=substr($str,$i,$n).chr(13).chr(10); $i+=$n; } else { $new_str.=$str; $i=strlen($str); } } return $new_str; } function loadfromfile($filename)//读出文件并编码 { $fp=fopen($filename,"rb"); $c=fread($fp,filesize($filename)); fclose($fp); return $this->str_row(base64_encode($c),77); } function file_header($filename)//给出文件头 { switch(substr($filename,strlen($filename)-3,3)) { case "gif": return "Content-Type: image/gif name="$filename""; break; case "jpg"; return "Content-Type: image/jpeg name="$filename""; break; case "txt"; return "Content-Type: text/plain name="$filename""; break; default: return "Content-Type: application/octetstream name="$filename""; } } function mail_body($str)//HTML部分 { $this->body.="--".$this->boundary2."
