What potential pitfalls can arise when trying to store directory contents in an array in PHP?

When trying to store directory contents in an array in PHP, potential pitfalls can arise if the directory is large and contains a large number of files. This can lead to memory consumption issues and slow performance. To solve this, it's recommended to use iterators or generators to process directory contents in a more memory-efficient way. 

$directory = '/path/to/directory';
$files = [];
$iterator = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($directory));

foreach ($iterator as $file) {
    if ($file->isFile()) {
        $files[] = $file->getPathname();
    }
}
