Are there any alternative methods or approaches to file inclusion in PHP that can help avoid variable scope issues?

When including files in PHP, variable scope issues can arise when variables defined in the included file are not accessible in the including file. One way to avoid this issue is to use the `include_once` or `require_once` functions, which ensure that the file is only included once, preventing any conflicts with variable names. Additionally, using functions or classes to encapsulate code can help avoid variable scope issues. 

// Using include_once to include the file
include_once 'included_file.php';

// Using a function to encapsulate code
function myFunction() {
    include 'included_file.php';
    
    // Code that uses variables from included_file.php
}
