Are there specific best practices for structuring PHP code to avoid issues like unwanted whitespace in the output?

Unwanted whitespace in the output of PHP code can be avoided by ensuring that there is no whitespace outside of the PHP opening and closing tags. This can be achieved by structuring the PHP code in a way that minimizes unnecessary spaces or line breaks. Additionally, using output buffering functions like ob_start() and ob_end_flush() can help control the output and remove any unwanted whitespace. 

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