Calculate directory size using 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:

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:

$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.

 

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:

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