How can differences in server environments, such as local development versus live hosting, impact the occurrence of header errors in PHP code?

Differences in server environments, such as local development versus live hosting, can impact the occurrence of header errors in PHP code due to variations in server configurations and settings. To mitigate this issue, it's important to ensure that the PHP code is written in a way that is compatible with different server environments and to test the code thoroughly in each environment before deployment.

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