这篇文章主要介绍了php带抄送和密件抄送的邮件发送方法,涉及php中mail函数的使用技巧,非常具有实用价值,需要的朋友可以参考下

本文实例讲述了php带抄送和密件抄送的邮件发送方法。具体分析如下：

程序中用到了php的mail函数，该函数定义如下：
bool mail ( string $to , string $subject , string $message [, string $additional_headers [, string $additional_parameters ]] )
如果邮件发送成功返回True，否则返回False

<html>
<head>
<title>Send email with CC and BCC</title>
</head>
<body>
<form action="sendemail.php" method=post name=form1>
<table>
  <tbody>
  <tr>
   <td>
    <p align=right><b>To</b></p></td>
   <td>
    <p>Name <input name=mailtoname size=35><br />E-mail
        <input name=mailtomail size=35></p></td></tr>
  <tr>
   <td>
    <p align=right><b>CC</b></p></td>
   <td><input name=mailcc size=35> </td></tr>
  <tr>
   <td>
    <p align=right><b>BCC</b></p></td>
   <td><input name=mailbcc size=35> </td></tr>
  <tr>
   <td>
    <p align=right><b>Priority</b></p></td>
   <td><select name=mailpriority>
      <option value=1>Highest</option>
      <option value=2>High</option>
      <option selected value=3>Normal</option>
      <option value=4>Low</option>
      <option value=5>Lowest</option>
     </select>
   </td></tr>
  <tr>
   <td><p align=right><b>Subject</b></p></td>
   <td><input name=mailsubject size=35></td></tr>
  <tr>
   <td>
    <p align=right><b>Message</b> </p></td>
   <td><textarea cols=50 name=mailbody rows=7></textarea></td></tr>
  <tr>
   <td colSpan=2>
    <p align=center>
 <input name=Submit type=submit value=Submit></p>
  </td>
  </tr>
  </tbody>
</table>
</form>
</body>
</html>

后端php代码，保存为sendmail.php

<html>
 <head>
 <title>Send Mail Script</title>
 </head>
 <body>
 <?php
  $message= " " ;
  if (empty ( $mailtoname) || empty ( $mailtomail) ) {
    die ( "Recipient is blank! ") ;
  }else{
    $to = $mailtoname . " <" . $mailtomail . ">" ;
  }
  if ( empty ( $mailsubject) ) {
   $mailsubject=" ";
  }
  if (($mailpriority>0) && ($mailpriority<6)) {
    $mailheader = "X-Priority: ". $mailpriority ."\n";
  }
  $mailheader.= "From: " . "Sales Team <sales@yourdomain.com>\n";
  $mailheader.= "X-Sender: " . "support@yourdomain.com\n";
  $mailheader.= "Return-Path: " . "support@yourdomain.com\n";
  if (!empty($mailcc)) {
   $mailheader.= "Cc: " . $mailcc ."\n";
  }
  if (!empty($mailbcc)) {
   $mailheader.= "Bcc: " . $mailbcc ."\n";
  }
  if (empty($mailbody)) {
   $mailbody=" ";
  }
  $result = mail ($to, $mailsubject, $mailbody, $mailheader);
  echo "<center><b>Mail sent to ". "$to". "<br />";
  echo $mailsubject. "<br />";
  echo $mailbody. "<br />";
  echo $mailheader. "<br />";
  if ($result) {
    echo "<p><b>Email sent successfully!</b></p>";
  }else{
    echo "<p><b>Email could not be sent. </b></p>";
  }
?>
<p align="center">
<table><tr><td width="66"><p align="right"><b>To</b></p></td>
       <td width="308"><b>
   <?php echo $mailtoname . " [". $mailtomail . " ]";?>
   </b></td></tr>
     <tr><td width="66"><p align="right"><b>CC</b></p></td>
       <td width="308"><b><?php echo $mailcc;?></b></td></tr>
     <tr><td width="66"><p align="right"><b>BCC</b></p></td>
       <td width="308"><b><?php echo $mailbcc; ?></b></td></tr>
     <tr><td width="66"><p align="right"><b>Priority</b></p></td>
       <td width="308"><b><?php echo $mailpriority;?></b></td></tr>
     <tr><td width="66"><p align="right"><b>Subject </b></p></td>
       <td width="308"><b><?php echo $mailsubject;?></b></td></tr>
     <tr><td width="66"><p align="right"><b>Message</b></p></td>
       <td width="308"><b><?php echo $mailbody;?></b></td></tr>
</table>
</p>
</body>
