How can line breaks be properly added to email messages generated in PHP scripts?

To add line breaks to email messages generated in PHP scripts, you can use the "\r\n" characters to indicate a new line. This ensures that the email content is displayed with proper line breaks when received by the recipient.

// Example PHP code snippet to add line breaks in an email message
$email_content = "Hello,\r\nThis is a test email message.\r\nThank you.";
mail($recipient_email, $subject, $email_content);
