Are there any best practices for handling empty directories in PHP?

When working with directories in PHP, it is important to handle cases where the directory may be empty. One way to check if a directory is empty is by using the glob() function to get a list of files in the directory and then checking if the resulting array is empty. If the directory is empty, you can perform any necessary actions such as deleting the directory or displaying a message to the user. 

$directory = '/path/to/directory';

// Get list of files in the directory
$files = glob($directory . '/*');

// Check if directory is empty
if (empty($files)) {
    // Perform actions for empty directory
    echo 'Directory is empty';
} else {
    // Directory is not empty
    // Proceed with other operations
}
