What are the best practices for using the "header("location:...")" function in PHP scripts to ensure smooth redirection?

When using the "header("location:...")" function in PHP scripts for redirection, it is important to ensure that there is no output sent to the browser before the header function is called. This can be achieved by placing the header function at the very beginning of the script, before any HTML or text output. Additionally, it is good practice to include an "exit();" statement immediately after the header function to prevent any further script execution. 

<?php
// Ensure no output is sent before header function
ob_start();

// Redirect to a new location
header("Location: https://www.example.com");

// Prevent any further script execution
exit();
?>
