Answer 1

http://us2.php.net/disk_total_space says,
"Given a string containing a directory, this function will return the total number of bytes on the corresponding filesystem or disk partition."
You're likely seeing the total_space of C:
Alternative solutions do exist for both Windows and Linux.

Answer 2

I think what you want is something like this:
function foldersize($path) {
$total_size = 0;
$files = scandir($path);
foreach($files as $t) {
if (is_dir(rtrim($path, '/') . '/' . $t)) {
if ($t<>"." && $t<>"..") {
$size = foldersize(rtrim($path, '/') . '/' . $t);
$total_size += $size;
}
} else {
$size = filesize(rtrim($path, '/') . '/' . $t);
$total_size += $size;
}
}
return $total_size;
}
function format_size($size) {
$mod = 1024;
$units = explode(' ','B KB MB GB TB PB');
for ($i = 0; $size > $mod; $i++) {
$size /= $mod;
}
return round($size, 2) . ' ' . $units[$i];
}
$SIZE_LIMIT = 5368709120; // 5 GB
$sql="select * from users order by id";
$result=mysql_query($sql);
while($row=mysql_fetch_array($result)) {
$disk_used = foldersize("C:/xampp/htdocs/freehosting/".$row['name']);
$disk_remaining = $SIZE_LIMIT - $disk_used;
print 'Name: ' . $row['name'] . '<br>';
print 'diskspace used: ' . format_size($disk_used) . '<br>';
print 'diskspace left: ' . format_size($disk_remaining) . '<br><hr>';
}
edit: the recursive function had a bug in it originally. Now it should also read folders inside the original folders, and folders inside those folders, and so on.

Answer 3

The comments on the function on PHP.net appear to indicate that this gives the space of the drive/partition $dir is in, not the size of $dir itself.

Answer 4

I think that method will only tell you information about the filesystem or partition the given directory is on. You could try simply shelling out to du though:
$space_used=`du -sh $dir`;
-s summarizes the entire dir, -h returns the result in "human" units like MB and GB.
Edit: apologies, I missed that this was on WIndows. WIll leave the answer in case it helps someone searching for a similar problem. For windows, try this suggestion in the PHP manual

Answer 5

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();
}

Answer 6

You could use the function:
function size_directory($ruta)
{
$gestor = opendir($ruta);
$total = 0;
while (($archivo = readdir($gestor)) !== false) {
$ruta_completa = $ruta . "/" . $archivo;
if ($archivo != "." && $archivo != "..") {
$total += filesize($ruta_completa);
}
}
return round($total / 1024, 0);
}
