I am trying to send email from my application using SwiftMailer. I have installed the SwiftMailer package using git with the following command in my project folder:

git clone

This showed me that swiftmailer is cloned properly in my project folder. Now when I am trying to send email from my application, it is showing the following error:

 <b>Parse error</b>:  syntax error, unexpected '?' in <b>C:\xampp\htdocs\myAppPath\swiftmailer\lib\classes\Swift\Transport\EsmtpTransport.php</b> on line <b>211</b><br />

When I tried to get into the EsmtpTransport.php file, I found the following code written:

 * Returns the IP used to connect to the destination.
 * @return string
public function getSourceIp()
    return $this->params['sourceIp'] ?? null;  //*line number 211*

The code I have written in my application is as below:

    $subject = 'SwiftMailer Test!';
    $message = 'Hi! This is a test email from SwiftMailer';
    $usernameEmail = "username";
    $passwordEmail = "password";
        $transport = (new Swift_SmtpTransport('', 25))
        $message = Swift_Message::newInstance();
        "" => "Recipient Name"
        $message->setFrom("", "My App Team");
        $mailer = Swift_Mailer::newInstance($transport);
        $mailer->send($message, $failedRecipients);

I am unable to figure out the issue and tried searching the net and unfortunately not successful yet. Can anyone please help? Thanks in advance!

    there's a typo in the code. They wanted to use ternary operator but instead : they put second ?. You doesn't use composer so you can just fix it yourself. Just change

    return $this->params['sourceIp'] ?? null;  //*line number 211*


    return $this->params['sourceIp'] ?: null;  //*line number 211*

    or download v6.0.1, free from this bug, from here.

    @edit It's not a typo. It's Null coalescing operator. It has been introduced in PHP7.0 so I suppose you're using an older version of PHP. You should use PHP7+ because swiftmailer is aimed for this versions.
