Hey.

You can use the DirectoryIterat or class to go over every file in a directory and find their sizes. Like this:

/**
 * Returns the total number of bytes for all files under the given directory.
 * @param string $path Path to the directory.
 * @return int
 */
function getDirectorySize($path) {
    $size = 0;
    $directory = new DirectoryIterator($path);
    foreach ($directory as $file) {
        if ($file->isFile()) {
            $size += $file->getSize();
        }
        else if (!$file->isDot() && $file->isDir()) {
            $size += getDirectorySize($file->getPathname());
        }
    }

    return $size;
}

However, if you are making some sort of file sharing/storing site with multiple users, each of which can store an X amount of data, then I wouldn't recommend this approach. It would be easier to manage this if you didn't store the user files separately, but simply saved them all in a common place and stored the paths to the files in a database. Then you could calculate how much space a user is using by doing a database query instead of having to read it from the actual hard drive.

if there are subfolders to check, the recursive version is a bit more convenient

/**
 * Returns the total number of bytes for all files under the given directory.
 * @param string $path Path to the directory.
 * @return int
 */
function getDirectorySize($path) {
    $size = 0;
    $directory = new RecursiveIteratorIterator(
        new RecursiveDirectoryIterator(
            $path, FilesystemIterator::SKIP_DOTS
        )
    );

    foreach ($directory as $file) {
        $size += $file->getSize();
    }
 
    return $size;
}

O yea, there was a recursive version of that iterator. Nice catch. I completely overlooked it.
