How can PHP be used to set a fixed sender email address in a mail form?

When creating a mail form in PHP, you may want to set a fixed sender email address to ensure all emails come from the same address. This can be achieved by using the 'From' header in the mail function. By setting the 'From' header to the desired email address, all emails sent from the form will appear to be sent from that address. 

$to = "recipient@example.com";
$subject = "Subject of the email";
$message = "This is the message content";

$from = "sender@example.com";
$headers = "From: $from";

// Send email
mail($to, $subject, $message, $headers);
