phpmailerHow do I set the boundary in PHPMailer?

PHPMailer is a library for sending emails. It can be used to set the boundary of an email, which is a string of characters that separates the different parts of the email.

To set the boundary in PHPMailer, you need to use the $mail->createHeader() method. This method takes two parameters, the first one being a string that contains the boundary string, and the second one being an array of headers.

Example code

$boundary = md5(time());
$mail->createHeader('Content-Type', ['boundary' => $boundary]);

The $boundary variable should be set to a unique string that is used to separate the different parts of the email. The md5() function is used to generate a unique string based on the current time.

The $mail->createHeader() method takes two parameters. The first parameter is a string that contains the boundary string. The second parameter is an array of headers, which is used to set the Content-Type header. The boundary string is set as a key in the array of headers.
