本文实例讲述了php简单实现发送带附件的邮件。分享给大家供大家参考。具体如下：
下面是静态html代码：
<html> <head> <title>带附件的邮件发送</title> </head> <body> <form method="post" name="form1" action="sendmail.php" ENCTYPE="multipart/form-data"> <table> <tr> <td>发送人：</td> <td><input type="text" name="from"></td> </tr> <tr> <td>收件人：</td> <td><input type="text" name="to"></td> </tr> <tr> <td>邮件主题：</td> <td><input type="text" name="subject"></td> </tr> <tr> <td>邮件内容：</td> <td><textarea name="body"></textarea></td> </tr> <tr> <td>附件上传：</td> <td><input type="file" name="upload_file"></td> </tr> <tr> <td span=2> <input type="submit" value="提交"> <input type="reset" value="重置"> </td> </tr> </table> </form> </body> </html>
sendmail.php文件代码：
<?php
//获得表单信息
$from = $_POST[‘from‘];
$to = $_POST[‘to‘];
$subject = $_POST[‘subject‘];
$body = $_POST[‘body‘];
// 定义分界线
$boundary = "345894369383"; //分界线是一串无规律的字符
//设置header
$header = "Content-type: multipart/mixed; boundary= $boundary/r/n";
$header .= "From:$from/r/n";
//获得上传文件的文件内容
$file = $_FILES[‘upload_file‘][‘tmp_name‘];
//确定上传文件的MIME类型
$mimeType = $_FILES[‘upload_file‘][‘type‘];
//获得上传文件的文件名
$fileName = $_FILES[‘upload_file‘][‘name‘];
//读取上传文件
$fp = fopen($file, "r"); //打开文件
$read = fread($fp, filesize($file)); //读入文件
$read = base64_encode($read); //base64编码
$read = chunk_split($read); //切割字符串
//建立邮件的主体，分为邮件内容和附件内容两部分
$body = "--$boundary
Content-type: text/plain; charset=iso-8859-1
Content-transfer-encoding: 8bit
$body
--$boundary
Content-type: $mimeType; name=$fileName
Content-disposition: attachment; filename=$fileName
Content-transfer-encoding: base64
$read
--$boundary--";
//发送邮件 并输出是否发送成功的信息
if(mail($to, $subject,$body,$header))
{
echo "信件发送成功";
}
else
{
echo "信件发送失败";
}
?>
希望本文所述对大家的php程序设计有所帮助。
