php - 在 php 中第二次发送不同的邮件时，如何删除附件表单 phpmailer

Question

在一个 php 文件中，我需要向 2 个不同的 ID 发送 2 封不同的电子邮件。当我使用如下所示的两个变量时，它不起作用。

require 'PHPmailer/class.phpmailer.php';

/* First Email*/

$email = new PHPMailer();
$email->From      = 'admin@mywebsite.com';
$email->FromName  = 'My Webisite';
$email->Subject   = 'Subject of first email';
$email->Body      = 'Body of the message to first person';
$email->AddAddress( 'to first person' );

$file_to_attach = 'path of the file';       
$email->AddAttachment( $file_to_attach, '' );

$email->Send();

/* Second Email*/

require 'PHPmailer/class.phpmailer.php';
$confirm = new PHPMailer();
$confirm-> From      = 'noreply@mywebsite.com';
$confirm-> FromName  = 'Admin @ MyWebsite';
$confirm-> Subject   = 'Subject of second email';
$confirm-> Body      = 'Body of second email';
$confirm-> AddAddress('Email ID of second person');

$confirm->Send();

但如果我两次使用同一个变量，我将按如下所示工作

require 'PHPmailer/class.phpmailer.php';

/* First Email*/

$email = new PHPMailer();
/* Same as above*/
$file_to_attach = 'path of the file';       
$email->AddAttachment( $file_to_attach, '' );

$email->Send();

/* Second Email*/

$email-> From      = 'noreply@mywebsite.com';
$email-> FromName  = 'Admin @ MyWebsite';
$email-> Subject   = 'Subject of second email';
$email-> Body      = 'Body of second email';
$email-> AddAddress('Email ID of second person');

$email->Send();

但问题是它将附件发送到两个电子邮件 ID。请帮助我如何不将附件发送到第二个 ID。

Answer 1

unset($mail->attachment) 将不起作用，因为 attachment 是一个 protected 变量。而是使用:

$email->clearAttachments();
