How can the issue of headers already being sent be resolved when using PHP forms?

When headers are already sent in PHP, it typically means that some content has already been output before header functions are called. To resolve this issue, you can ensure that no content is output before calling header functions by placing the header functions at the beginning of the script or using output buffering. 

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

// Your PHP code here

ob_end_flush(); // Flush the output buffer
?>
