php带抄送和密件抄送的邮件发送方法_PHP

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

后端php代码，保存为sendmail.php

 
 
 
 
 <?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 \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, $mailheader);
  echo "Mail sent to ". "$to". "
