What are the potential pitfalls of using opendir to open directories in PHP?

One potential pitfall of using opendir in PHP is that it does not handle errors or exceptions gracefully, which can lead to unexpected behavior or crashes in your application. To solve this issue, you can use the directory iterator class in PHP, which provides a more object-oriented and robust way to iterate over directory contents. 

// Using DirectoryIterator to open directories in PHP
$directory = new DirectoryIterator('/path/to/directory');

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