How can the DirectoryIterator class be utilized to improve directory scanning functions in PHP?

Directory scanning functions in PHP can be improved by using the DirectoryIterator class, which provides an object-oriented interface for iterating over directory contents. This class offers a more flexible and efficient way to scan directories compared to traditional functions like scandir() or glob(). 

// Using DirectoryIterator to scan a directory
$directory = new DirectoryIterator('/path/to/directory');

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