How can the issue of modifying header information be prevented or resolved in PHP scripts?

To prevent or resolve the issue of modifying header information in PHP scripts, ensure that no output is sent to the browser before calling the header() function. This can be achieved by placing the header() function at the beginning of the script before any other output. 

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

// Place header() function at the beginning of the script
header('Content-Type: text/html');

// Your PHP code goes here

ob_end_flush(); // Flush output buffer
?>
