How can the output of functions be managed to avoid header modification errors in PHP scripts?

To avoid header modification errors in PHP scripts, it is important to ensure that no output is sent before calling functions like header(). This can be achieved by using output buffering to capture any output before headers are sent. By buffering the output, you can modify headers without encountering errors. 

<?php
ob_start(); // Start output buffering

// Your PHP code here

ob_end_flush(); // Flush the output buffer
