What are the advantages and disadvantages of using DirectoryIterator in PHP for file manipulation tasks?

When working with file manipulation tasks in PHP, using the DirectoryIterator class can be beneficial as it provides an object-oriented interface for iterating over the contents of a directory. This can simplify tasks such as listing files, filtering specific file types, and performing operations on each file. However, one disadvantage of using DirectoryIterator is that it may not be as efficient as using lower-level functions like scandir() or glob() for simple directory operations. 

// Example of using DirectoryIterator to list all files in a directory
$directory = new DirectoryIterator('/path/to/directory');

foreach ($directory as $fileInfo) {
    if ($fileInfo->isFile()) {
        echo $fileInfo->getFilename() . "\n";
    }
}
