What are potential issues with using similar variables in PHP mailer code?

Using similar variables in PHP mailer code can lead to confusion and errors, especially when trying to differentiate between them. To avoid this issue, it is best practice to use clear and distinct variable names that accurately represent their purpose in the code. 

// Bad practice: using similar variables
$to = "recipient@example.com";
$subject = "Subject";
$message = "Message";
$headers = "From: sender@example.com";

// Good practice: using distinct variable names
$recipient_email = "recipient@example.com";
$email_subject = "Subject";
$email_message = "Message";
$email_headers = "From: sender@example.com";
