How can PHP developers ensure that empty directories are not skipped when iterating through directories?

When iterating through directories in PHP, empty directories may be skipped because the `scandir()` function does not return entries for empty directories. To ensure that empty directories are not skipped, developers can use the `glob()` function with the GLOB_ONLYDIR flag to specifically retrieve directories, including empty ones. 

$directories = glob('*', GLOB_ONLYDIR);
foreach ($directories as $directory) {
    // Process each directory, including empty ones
}
