How can nested folders and subfolders affect the accuracy of calculating folder sizes in PHP?

Nested folders and subfolders can affect the accuracy of calculating folder sizes in PHP because the script may not account for all subfolders and files within the nested structure. To accurately calculate folder sizes, you can recursively iterate through all folders and subfolders, summing up the sizes of each file along the way. 

function get_folder_size($path){
    $total_size = 0;
    
    foreach(new RecursiveIteratorIterator(new RecursiveDirectoryIterator($path)) as $file){
        $total_size += $file->getSize();
    }
    
    return $total_size;
}

// Usage example
$folder_path = '/path/to/your/folder';
$folder_size = get_folder_size($folder_path);
echo "Folder size: " . $folder_size . " bytes";
