How can PHP scripts be structured to prevent header modification issues?

To prevent header modification issues in PHP scripts, it is important to ensure that no output is sent to the browser before calling the header() function. This can be achieved by structuring the script in a way that all header-related functions are called before any content is echoed or printed to the browser. 

<?php
// Set headers before any output
header("Content-Type: text/html");

// Start session before any output
session_start();

// Other header-related functions can go here

// Output content after headers are set
echo "Hello, World!";
?>
