What are the risks of deleting files that are not included but still used in a PHP project?

Deleting files that are not explicitly included but still used in a PHP project can lead to unexpected errors or functionality breakage. To mitigate this risk, it is important to thoroughly review the project's codebase and ensure that all files being used are accounted for in the project structure. 

// Example of checking for file existence before including it in PHP
$file_path = 'path/to/file.php';

if (file_exists($file_path)) {
    include $file_path;
} else {
    // Handle error or log a warning
    echo 'File does not exist: ' . $file_path;
}
