Question

I want to verify files stored in a directory, so i wrote this script.

<?php
$files = scandir('..');
for ($i=0;$i<count($files);$i++)
{
 $file2 = realpath($files[$i]);
 if (!is_dir($file2))
  $hash = sha1_file($file2);
 else
  $hash = 'Dir';
 echo '<tr><td>'.$i.'</td><td>'.$file2.'</td><td>'.$hash.'</td><td>'.date ("F d Y H:i:s.",filemtime($file2)).'</td></tr>';
 $i;
}
?>

it works nice, but if i include this script from a deeper a directory then it fails.

-www
 |_Sou
   |_Inner
     |_MoreInner

my script is located in inner folder and want to access it from MoreInner folder using include but it shows error FILE NOT FOUND/ PERMISSION DENIED

• What i want to do
  To get SHA1_FILE of files stored in the just above directory.

Using a RecurisveDirectoryIterator would be the most elegant way:

$it = new RecursiveDirectoryIterator('..', FilesystemIterator::CURRENT_AS_FILEINFO | FilesystemIterator::SKIP_DOTS);
foreach (new RecursiveIteratorIterator($it, RecursiveIteratorIterator::SELF_FIRST) as $item) {
    if (!$item->isDir()) {
        $hash = sha1_file($item->getRealPath());
    } else {
        $hash = 'Dir';
    }
    echo $item->getRealPath().' '.$hash.' '.date ("F d Y H:i:s.", $item->getMTime())."\n";
}
