What are some best practices for handling file paths and file names when using RecursiveIteratorIterator in PHP?

When using RecursiveIteratorIterator in PHP to iterate over files and directories, it is important to handle file paths and file names properly to avoid issues with different operating systems and file systems. To ensure compatibility and avoid errors, it is recommended to use the DIRECTORY_SEPARATOR constant for building file paths and the basename() function for extracting file names. 

$directory = '/path/to/directory';

$iterator = new RecursiveIteratorIterator(
    new RecursiveDirectoryIterator($directory, RecursiveDirectoryIterator::SKIP_DOTS),
    RecursiveIteratorIterator::SELF_FIRST
);

foreach ($iterator as $file) {
    $filePath = $file->getPath() . DIRECTORY_SEPARATOR . $file->getFilename();
    $fileName = basename($file->getFilename());

    // Handle file path and file name as needed
}
