What is the significance of saving a PHP file as "UTF-8 without BOM" to prevent header modification errors?

When saving a PHP file as "UTF-8 without BOM," it ensures that no Byte Order Mark (BOM) characters are added at the beginning of the file. These characters can cause header modification errors in PHP scripts, as they are treated as output before headers are sent. By saving the file in this format, you prevent any unwanted characters from interfering with the header modification process. 

<?php
ob_start();
// Your PHP code here
ob_end_clean();
?>
