What are the potential drawbacks of using opendir and readdir functions in PHP to read directory contents?

One potential drawback of using opendir and readdir functions in PHP to read directory contents is that they are procedural and may not be as efficient or easy to use as newer object-oriented alternatives like the DirectoryIterator class. To overcome this, you can use the DirectoryIterator class which provides a more object-oriented approach to iterating over directory contents. 

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

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