What are the advantages of using placeholders in email content instead of directly embedding data in PHP scripts?

Using placeholders in email content instead of directly embedding data in PHP scripts allows for easier customization and updating of email templates. It also helps to separate content from code, making it easier to maintain and modify the email content without having to touch the PHP code. Additionally, placeholders can help prevent injection attacks and ensure data integrity in the email content. 

// Using placeholders in email content
$emailContent = "Hello {name}, thank you for signing up for our newsletter!";
$emailContent = str_replace('{name}', $userName, $emailContent);

// Sending email
$to = "recipient@example.com";
$subject = "Welcome to our newsletter!";
$headers = "From: yourname@example.com";
mail($to, $subject, $emailContent, $headers);
