        // Display the file name and
        // inode change time
        echo $file->getFilename() . " | CTime: "
                . $directory->getCTime() . "<br>";
    }

    // Move to the next element

}
?>

Output:

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

Program 2:

<?php

$directory = new DirectoryIterator(dirname(__FILE__));

// Loop runs for each element of directory
foreach($directory as $dir) {

    // Store the current element of directory
    $file = $directory->current();

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

Output:

0 => . | CTime: 1574350718
