php实现的发送带附件邮件类实例，附件实例
本文实例讲述了php实现的发送带附件邮件类的方法，是一个非常实用的功能。分享给大家供大家参考。具体方法如下：
emailclass.php类文件如下：
<?
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,$headers);
}
function write_body($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
*/
?>
Demo示例文件如下：
<?php
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
$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();
?>
相信本文所述对大家php程序设计的学习有一定的借鉴价值。
直接发是不行的，用phpmailer
/*
$to 目标
$subject 主题
$message 正文
$from 发自
$content_type 类型
$attache 附件，文件名放在数组中
*/
$email = $_POST['email'];
$email = trim("$email");
$message = "hello";
function mail2( $to, $subject, $message, $from, $content_type, $attache="") {
if(!empty($from)) $head = "From: $from\n";
if(empty($content_type)) $content_type = "text/plain";
if(is_array($attache)) {
$boundary = "===" . md5(uniqid("")) . "===";
$head .= "Mime-Version: 1.0\nContent-Type: multipart/mixed; boundary=\"";
$head .= "$boundary\"\n\nThis is a multi-part message in MIME format.\n\n";
$head .= "--$boundary\n";
$head .= "Content-Type: $content_type\n";
$head .= "\n$message\n\n";
while(list($key, $val) = each($attache)) {
$fd = fopen("$val", "r") or die("unable to open file $val");
$contents = chunk_split(base64_encode(fread($fd,filesize("$val"))));
fclose($fd);
