面向对象的php邮件

我想通过php代码发送邮件。我熟悉过程，但我是面向对象（OOP）的新手。我的邮件代码在过程bt中运行良好，而不是在OOP中

if(isset($_REQUEST['send']))
{
$name=$_REQUEST['name'];
$email=$_REQUEST['email'];
$phone=$_REQUEST['phone'];
$message=$_REQUEST['message'];
include "config.php";
 $sql = $conn->query("insert into message(name,email,phone,message) values ('$name','$email','$phone','$message')");

 $from = $email;
     $to= 'web@gmail.com';
     $headers1 = "From: $from\n";
echo     $body = "
 Hello Sir,
 I request you to give authority to access parkintrade website as guest     user.

  user Details
   Name    : $name
   Email   : $email
   Phone   : $phone
   message : $message
 ";
  $body.="\nThis is an auto generated email so please do not reply to this email.
  Thank you,
  $name\n";

 echo  $sentmail = mail( $to,"Welcome ", $body, $headers1 );
}

启发自己。

“指导我如何在OOP中发送邮件”有707点，我觉得我可以毫无遗憾地说：不，所以不是来转换代码或提供教程的，用谷歌搜索并学习它。有“致命错误：找不到类'PHPMailer'”即使我复制了class.phpmailer.phpLike@Epodax，也不是为了转换代码或提供教程，用谷歌搜索并学习它
