calculating total size in kbytes of a folder and all subfolders (Windows)

[Brian_A]

Yes, yet another newbie question. In PHP I an get the size of a file/image but how can I obtain the size of all folders and files within in an entire branch of a directory tree?

In other words:

folder1
|folder2
|folder3
| |folder4
|folder5

What would the contents total size for folder1 be? How do I calculate that without knowing the tree structure?

Thank you so much for your help on this problem.

this might be a good foundation to work off of.. this was an old sitemap function i found and just made it add the dir name to $sizes, and attempt to add the file sizes as its value..

run it and you should know what i mean- its not 100% accurate, and i dont wanna play with it , im tired 🙂

function dirsize($dir){
	$sizes=array();
	$handle=opendir($dir);
	while($file=readdir($handle))
		$retVal[]=$file;
	closedir($handle);
	sort($retVal);

foreach($retVal as $k=>$v)
{
	if($v!="." && $v!=".."):
		if(is_dir("$dir/$v"))
			dirsize("$dir/$v");
		else
			if(!in_array($dir,$sizes))
				@$sizes[$dir]+=filesize("$dir/$v");
	endif;
}
print_r($sizes);
}
dirsize(".");

it was off by maybe a hundred or so bytes.. to get the kb just add in a line like @$sizes+=(filesize("$dir/$v")/1024);

Thank you for the script, it has been educational but what is the link that I am missing here, I do not see how I could tally up the total bytes so that I could display a content total.

I see that the values are put into an array, but yet I don't see how to also keep a sum total.

The accuracy is not critical as long as it is close. I just want to ensure that specified directory (all contents) don't go over an approximate value.

So, if I am correct I need to keep a running tally of each but I don't quite honestly know how.

Thank you much for all your other advice, it has been fantastic!!!!

Okay, the output is (in my case):

Array ( [./files/sigs] => 129.30078125 ) Array ( [./files/temp] => 30.9736328125 ) Array ( [./files] => 20.1044921875 ) Array ( [./sigs/temp] => 7.12890625 ) Array ( [./sigs] => 167.689453125 ) Array ( [.] => 76.4501953125 )

I see that the totals (in kbytes) for each subdir is, for example, 129, 30, 20, 7, 167, and 76 respectively.

I am still unclear on how to add these values into one single variable so that I can then show disk uage for the entire sub-domain user.

I don't know why I find arrays so baffling, but honestly I can see the solution but not quite get there (newbies, what can ya do?).

Thanks for all your help.

maybe something like

foreach($sizes as $k=>$v)
{
 static $tkb=0;
 $tkb+=(int)$v;
}
echo "Total dir size for $dir is " . $tkb/1024 . "KB";

??

it was giving me funny results, but then again- i have a huge dir im testing it in 🙂

Thanks again, I had come up with the following myself which is in the ball park of what you recommend.

global $diskuse;
foreach ( $sizes as $value )
{
$diskuse += $value;
}

... then I convert to an integer when I display it.

I try your method, too. I sure do appreciate your help.

🆒
