php实现邮件发送并带有附件

emailclass.php

复制代码 代码如下:

<? 

class CMailFile {

var $subject; 

var $addr_to; 

var $text_body; 

var $text_encoded; 

var $mime_headers; 

var $mime_boundary = "--==================_846811060==_"; 

var $smtp_headers;

function CMailFile($subject,$to,$from,$msg,$filename,$downfilename,$mimetype = "application/octet-stream",$mime_filename = false) { 

$this->subject = $subject; 

$this->addr_to = $to; 

$this->smtp_headers = $this->write_smtpheaders($from); 

$this->text_body = $this->write_body($msg); 

$this->text_encoded = $this->attach_file($filename,$downfilename,$mimetype,$mime_filename); 

$this->mime_headers = $this->write_mimeheaders($filename, $mime_filename); 

}

function attach_file($filename,$downfilename,$mimetype,$mime_filename) { 

$encoded = $this->encode_file($filename); 

if ($mime_filename) $filename = $mime_filename; 

$out = "--" . $this->mime_boundary . "\n"; 

$out = $out . "Content-type: " . $mimetype . "; name=\"$filename\";\n"; 

$out = $out . "Content-Transfer-Encoding: base64\n"; 

$out = $out . "Content-disposition: attachment; filename=\"$downfilename\"\n\n"; 

$out = $out . $encoded . "\n"; 

$out = $out . "--" . $this->mime_boundary . "--" . "\n"; 

return $out; 

}

function encode_file($sourcefile) { 

if (is_readable($sourcefile)) { 

$fd = fopen($sourcefile, "r"); 

$contents = fread($fd, filesize($sourcefile)); 

$encoded = chunk_split(base64_encode($contents)); 

fclose($fd); 

} 

return $encoded; 

}

function sendfile() { 

$headers = $this->smtp_headers . $this->mime_headers; 

$message = $this->text_body . $this->text_encoded; 

mail($this->addr_to,$this->subject,$message,$headers); 

} www.jbxue.com

function write_body($msgtext) { 

$out = "--" . $this->mime_boundary . "\n"; 

$out = $out . "Content-Type: text/plain; charset=\"us-ascii\"\n\n"; 

$out = $out . $msgtext . "\n"; 

return $out; 

}

function write_mimeheaders($filename, $mime_filename) { 

if ($mime_filename) $filename = $mime_filename; 

$out = "MIME-version: 1.0\n"; 

$out = $out . "Content-type: multipart/mixed; "; 

$out = $out . "boundary=\"$this->mime_boundary\"\n"; 

$out = $out . "Content-transfer-encoding: 7BIT\n"; 

$out = $out . "X-attachments: $filename;\n\n"; 

return $out; 

}

function write_smtpheaders($addr_from) { 

$out = "From: $addr_from\n"; 

$out = $out . "Reply-To: $addr_from\n"; 

$out = $out . "X-Mailer: PHP3\n"; 

$out = $out . "X-Sender: $addr_from\n"; 

return $out; 

} 

}

/*用法 - 例如:mimetype 为 "image/gif" 

$mailfile = new CMailFile($subject,$sendto,$replyto,$message,$filename,$mimetype); 

$mailfile->sendfile();

$subject -- 主题 

$sendto -- 收信人地址 

$replyto -- 回复地址 

$message -- 信件内容 

$filename -- 附件文件名 

$downfilename -- 下載的文件名 

$mimetype -- mime类型
