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->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.php.net

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
*/
?>

演示示例

复制代码 代码如下:

require_once('emailclass.php');

//发送邮件

//主題
$subject = "test send email";

//收件人
$sendto = 'abc@163.com';

//發件人
$replyto = 'cdf@163.com';

//內容 www.php.net
$message = "test send email content";

//附件
$filename = 'test.jpg';

//附件類別
$mimetype = "image/jpeg";

$mailfile = new CMailFile($subject,$sendto,$replyto,$message,$filename,$excelname,$mimetype);
$mailfile->sendfile();
?>
