i have this on my code

Answer 1

According to the docs for disk_total_space(), the value returned is for the filesystem the directory is located on. It doesn't count the space used in a directory + its subdirectories.

You could shell out to du or for a more portable solution:

$total = 0;

foreach (new RecursiveDirectoryIterator($dir) as $entry)
{
    if ($entry->isFile())
        $total += $entry->getSize();
}
