PHP function to get the folder size including subfolders

foldersize.php

<?php

function folderSize ($dir)
{
    $size = 0;

    foreach (glob(rtrim($dir, '/').'/*', GLOB_NOSORT) as $each) {
        $size += is_file($each) ? filesize($each) : folderSize($each);
    }

    return $size;
}

well Done! And thank you :)

awasome function 👍 💯

The result is in bytes or KB? Thank you!

@mdimitris " bytes"
Hope you must have got the answer 😄

Thanks

Thanks

many thanks.

hi what is folderSize($each); I think this one should be undefined

@sakonachhoeurng Hi, you probably noticed already) but just in case, It's the function name - recursive call, to count all subfolders as fell.

Perfect.

Perfect - thanks for your help!

Nice, however, at least on Linux, it won't include dot-files (since * does not match .some-file). Furthermore, on my machine an empty directory still occupies some space (4096 bytes according to du), this is also not included in folderSize.

Oh, and thanks, I'm using something very similar.

Cool thank you

Thanks! It helps me a lot.

For directory size:
if($size<1024){$size=$size." Bytes";}
elseif(($size<1048576)&&($size>1023)){$size=round($size/1024, 1)." KB";}
elseif(($size<1073741824)&&($size>1048575)){$size=round($size/1048576, 1)." MB";}
else{$size=round($size/1073741824, 1)." GB";}
return $size;

Thanks a lot

Great, thanks! Using this!

Nice but nothing beats the Swag of the following when the directory size is large.

    $f = './path/directory';
    $io = popen ( '/usr/bin/du -sk ' . $f, 'r' );
    $size = fgets ( $io, 4096);
    $size = substr ( $size, 0, strpos ( $size, "\t" ) );
    pclose ( $io );
    echo 'Directory: ' . $f . ' => Size: ' . $size;

Gracias!!

@eusonlito Perfect 👍

Regards,
some fast solution for Windows?

This function converts bytes:

function sizeFilter($bytes)
    {
        $label = array('B', 'KB', 'MB', 'GB', 'TB', 'PB');

        for ($i = 0; $bytes >= 1024 && $i < (count($label) - 1); $bytes /= 1024, $i++) ;

        return (round($bytes, 2) . " " . $label[$i]);
    }

Perfect..

Great!

Va perfecto, gracias 👍

-h, --human-readable print sizes in human readable format (e.g., 1K 234M 2G)

    $f = './path/directory';
    $io = popen ( '/usr/bin/du -sh ' . $f, 'r' );
    $size = fgets ( $io, 4096);
    $size = substr ( $size, 0, strpos ( $size, "\t" ) );
    pclose ( $io );
    echo 'Directory: ' . $f . ' => Size: ' . $size;

In GigaBytes:

return $size / 1e-9; //GigaBytes
