How can PHP developers ensure that the subject and sender email address are properly displayed in emails sent using PHP?

When sending emails using PHP, developers can ensure that the subject and sender email address are properly displayed by setting the appropriate headers in the mail function. This includes setting the "From" header to specify the sender's email address and name, as well as setting the "Subject" header to define the email subject. 

$to = "recipient@example.com";
$subject = "Email Subject";
$message = "This is a test email.";
$headers = "From: Sender Name <sender@example.com>\r\n";
$headers .= "Reply-To: sender@example.com\r\n";
$headers .= "MIME-Version: 1.0\r\n";
$headers .= "Content-type: text/html; charset=iso-8859-1\r\n";

mail($to, $subject, $message, $headers);
