How can developers ensure that their PHP code is properly synchronized with the browser display during development?

To ensure that PHP code is properly synchronized with the browser display during development, developers can use PHP output buffering. This allows the PHP script to buffer its output instead of sending it directly to the browser, giving developers more control over when content is sent. By using output buffering, developers can ensure that all PHP code is executed before any content is displayed in the browser.

<?php
ob_start();

// PHP code goes here

ob_end_flush();
?>
