How can the $thisdir variable be used effectively in PHP to manipulate file paths?

When working with file paths in PHP, the $thisdir variable can be used to reference the current directory of the script. This can be especially useful when constructing paths to include or require files relative to the current script's location. By using $thisdir, you can ensure that your file paths are always correct regardless of where the script is located. 

$thisdir = dirname(__FILE__);
$include_path = $thisdir . '/includes/header.php';
require_once($include_path);
