Are there best practices for managing function calls within PHP to avoid unwanted output from previous functions?

When managing function calls within PHP, one way to avoid unwanted output from previous functions is to use output buffering. By capturing the output of functions in a buffer, you can control when and where the output is displayed. This can be particularly useful when dealing with functions that generate output that you don't want to be displayed immediately. 

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

// Call functions that may generate unwanted output
function1();
function2();

ob_end_clean(); // Discard the output buffer without displaying it

// Continue with the rest of your code
?>
