Is there a more efficient way to include files in PHP that allows for independent sections on a webpage without the need to adjust paths manually?

When including files in PHP for independent sections on a webpage, it is more efficient to use the `__DIR__` magic constant to automatically adjust file paths. By using `__DIR__`, you can ensure that the included files are referenced correctly regardless of the directory structure.

<?php
include __DIR__ . '/header.php';
include __DIR__ . '/sidebar.php';
include __DIR__ . '/content.php';
include __DIR__ . '/footer.php';
?>
