What is the best way to rename folders in PHP?

When renaming folders in PHP, you can use the `rename()` function. This function takes two parameters: the current name of the folder and the new name you want to give it. Make sure to include the full path for both the current and new folder names to ensure the correct folders are targeted for renaming.

$old_folder = '/path/to/current/folder';
$new_folder = '/path/to/new/folder';

if (rename($old_folder, $new_folder)) {
    echo "Folder renamed successfully.";
} else {
    echo "Error renaming folder.";
}
