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;
}

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 👍

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
