How can understanding the current working directory in PHP help resolve file inclusion issues?

When including files in PHP, it's important to understand the current working directory because file paths are relative to this directory. If the current working directory is not what you expect, it can lead to file inclusion issues where PHP can't find the files you're trying to include. To resolve this, you can use the `__DIR__` or `dirname(__FILE__)` magic constants to get the absolute path of the current script's directory and build file paths relative to that. 

// Get the absolute path of the current script's directory
$dir = __DIR__;

// Include a file using the absolute path
include $dir . '/path/to/file.php';
