What are best practices for managing PHP includes in a project?

Managing PHP includes in a project involves organizing and structuring your code in a way that promotes reusability and maintainability. It is important to create separate files for different functionalities and include them where needed using include or require statements. Additionally, using autoloading mechanisms like Composer's PSR-4 can help streamline the process of including files in your project.

// Example of including a file in PHP
include 'path/to/file.php';
