Calculate directory size using PHP

This is an article on Calculate directory size using PHP in PHP.
I was wondering whether i could read the size of a directory using PHP. So i thought of making something which could help me read the size of the directory ,no. of directories and the no. of files in the given diretory.
The function "getDirectorySize" will ignore link/shorcuts to files/directory.
The function "sizeFormat" will suffix the size with bytes,KB,MB or GB accordingly.

Here is the code:

PHP Code:
function getDirectorySize($path)
{
  $totalsize = 0;
  $totalcount = 0;
  $dircount = 0;
  if ($handle = opendir ($path))
  {
    while (false !== ($file = readdir($handle)))
    {
      $nextpath = $path . '/' . $file;
      if ($file != '.' && $file != '..' && !is_link ($nextpath))
      {
        if (is_dir ($nextpath))
        {
          $dircount++;
          $result = getDirectorySize($nextpath);
          $totalsize += $result['size'];
          $totalcount += $result['count'];
          $dircount += $result['dircount'];
        }
        elseif (is_file ($nextpath))
        {
          $totalsize += filesize ($nextpath);
          $totalcount++;
        }
      }
    }
  }
  closedir ($handle);
  $total['size'] = $totalsize;
  $total['count'] = $totalcount;
  $total['dircount'] = $dircount;
  return $total;
}

function sizeFormat($size)
{
    if($size<1024)
    {
        return $size." bytes";
    }
    else if($size<(1024*1024))
    {
        $size=round($size/1024,1);
        return $size." KB";
    }
    else if($size<(1024*1024*1024))
    {
        $size=round($size/(1024*1024),1);
        return $size." MB";
    }
    else
    {
        $size=round($size/(1024*1024*1024),1);
        return $size." GB";
    }

} 
Example code:

PHP Code:
$path="/httpd/html/pradeep/";
$ar=getDirectorySize($path);

echo "<h4>Details for the path : $path</h4>";
echo "Total size : ".sizeFormat($ar['size'])."<br>";
echo "No. of files : ".$ar['count']."<br>";
echo "No. of directories : ".$ar['dircount']."<br>"; 
Output:
Details for the path : /httpd/html/pradeep/
Total size : 2.9 MB
No. of files : 196
No. of directories : 20

May I use this code on a web site? Is there some kind of copyright or credit notice I should include? Thanks.

Refer to the last line in the article which says what you should be doing. It should link to the forum and the link should be live and click-able.

Thanks. I wasn't sure because that line is referring to use the article, complete and unaltered. I'm not really using the article, just the code. I wasn't sure what the "resource box" was either. So if I just include a live link back to this thread, would that be acceptable?

You actually can. Go search for the codes, you will need that to do have it calculated. The URL is not working. Can you PM another link for this? Thank you!

It is good, but I would use the later source code.

PHP Code:
   $result=explode("\t",exec("du -hs ".$path),2);
    $result[1]==$path ? $result[0] : "error";
    echo $result[1];
