What are the best practices for managing included files in PHP to prevent conflicts between them?

When including multiple files in PHP, it's important to avoid naming conflicts between them. One way to prevent conflicts is to use unique prefixes or namespaces for functions, classes, and variables in each included file. This helps ensure that identifiers do not clash and cause unexpected behavior in your application. 

// File1.php
function file1_function() {
    echo "Function from File1";
}

// File2.php
function file2_function() {
    echo "Function from File2";
}

// index.php
include 'File1.php';
include 'File2.php';

file1_function(); // Output: Function from File1
file2_function(); // Output: Function from File2
