        // Store the current element 
        $file = $directory->current(); 
  
        // Display the file name and  
        // inode change time 
        echo $file->getFilename() . " | CTime: "
                . $directory->getCTime() . "<br>"; 
    } 
  
    // Move to the next element

    // Display the key, filename and  
    // its inode change time 
    echo $dir->key() . " => " .  
        $file->getFilename() . " | CTime: " . 
        $dir->getCTime() . "<br>"; 
} 
?>

输出：
