.. | CTime: 1574350715
dashboard | CTime: 1574350718
img | CTime: 1574350718
webalizer | CTime: 1574350718

Program 2:




<?php

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