sendmail.php文件代碼：

<?php  
//獲得表單信息 
$from = $_POST['from']; 
$to = $_POST['to'];  
$subject = $_POST['subject'];  
$body = $_POST['body'];  
// 定義分界線  
$boundary = "345894369383"; //分界線是一串無規(guī)律的字符 
//設置header 
$header = "Content-type: multipart/mixed; boundary= $boundary/r/n";  
$header .= "From:$from/r/n";  
//獲得上傳文件的文件內(nèi)容 
$file = $_FILES['upload_file']['tmp_name'];  
//確定上傳文件的MIME類型  
$mimeType = $_FILES['upload_file']['type'];  
//獲得上傳文件的文件名  
$fileName = $_FILES['upload_file']['name'];  
//讀取上傳文件  
$fp = fopen($file, "r"); //打開文件 
$read = fread($fp, filesize($file)); //讀入文件 
$read = base64_encode($read); //base64編碼  
$read = chunk_split($read); //切割字符串 
//建立郵件的主體，分為郵件內(nèi)容和附件內(nèi)容兩部分 
$body = "--$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--";  
//發(fā)送郵件 并輸出是否發(fā)送成功的信息 
if(mail($to, $subject,$body,$header))  
{ 
  echo "信件發(fā)送成功";
