Swiftmailer和PHP变量

我有以下代码：

<?php
include 'swiftmailer/lib/swift_required.php';
//*** Create the Transport ***
$transport = Swift_SmtpTransport::newInstance('smtp.My-Hosting', 25)
->setUsername('MyUserName')
->setPassword('Password');
//*** Create the Mailer using your created Transport ***
$mailer = Swift_Mailer::newInstance($transport);
//*** Create a message ***
$message = Swift_Message::newInstance('NameOfInstance')
->setFrom(array('Support@test.com' => 'John Doe'))
->setTo(array("John@test.com" => "John Smith"))
->setBody('This is a test email message') ;
//*** Send the message ***
$result = $mailer->send($message);
?>

---

如何在setFrom、setTo和setBody数组中使用PHP变量（即$email、$name等）？（我不想键入个人电子邮件/姓名）

如果我理解您的问题和代码（因为它是未格式化的），您应该能够简单地用您选择的变量名替换字符串

例如，已格式化的原始代码是：

setUsername('MyUserName') ->setPassword('Password'); 
//*** Create the Mailer using your created Transport *** 
$mailer = Swift_Mailer::newInstance($transport); 
//*** Create a message *** 
$message = Swift_Message::newInstance('NameOfInstance') ->setFrom(array('Support@test.com' => 'John Doe')) ->setTo(array("John@test.com" => "John Smith")) ->setBody('This is a test email message') ; 
//*** Send the message *** 
$result = $mailer->send($message); 

现在，您只需更换“John@test.com“使用$from_电子邮件或您选择的任何变量名称。。。以及其他文本字符串

setUsername('MyUserName')->setPassword('Password'); 
//*** Create the Mailer using your created Transport *** 
$mailer = Swift_Mailer::newInstance($transport); 
//*** Create a message *** 
$message = Swift_Message::newInstance('NameOfInstance')->
    setFrom(array($from_email => $from_name))->
    setTo(array($to_email => $to_name))->setBody($body) ; 
//*** Send the message *** 
$result = $mailer->send($message);
