What are the common mistakes or misunderstandings that developers may encounter when working with PHP headers for page redirection, and how can these be addressed effectively?

One common mistake when working with PHP headers for page redirection is attempting to set headers after output has already been sent to the browser. This can result in a "headers already sent" error. To address this, make sure to set headers before any output is sent, such as before any HTML content or whitespace. 

<?php
// Correct way to redirect using PHP headers
header("Location: https://www.example.com");
exit;
?>
