hi 2 all,

i want to know about such a script that allow me to see the used space on the server of certain folders or directories.

suppose i have 'test' directory on my www.domain.com/
then i want php to show how much this dir has used space

i used disk_total_space() function but it shows whole server space

pls anyone knows this then let me know

Thanks

I'm thinking that the only way to do this is to loop through the directory and use filesize [us3.php.net] to sum up the size of each file.

There may be pre-made classes for something like this. You can always check the script repositories(hotscripts, sourceforge, etc...) or phpclasses.org

[edit]
Here's one [phpclasses.org] I found real quick. I have never used it, but if it saves you time you might want to look into it.

assuming a unix-like system you could possibly use the du command.

try something like du -sk /directory/name

To get to a unix command from php:

system(): [php.net...]

To write the function yourself:

define a function.

In the function, open the directory with
opendir() [php.net...]

next iterate in a loop over all the entries in that directory

skip over the . and .. entries

add their size and if you see a subdir, you can recursively call this function again ...

close the directory

return the accumulated size to the caller.

There's plenty of samples contributed on the opendir page to get you started.

The command to get to the size of a file or directory (directories do take up diskspace for themselves too!)
is stat() [php.net...] it returns an array of which the [7] is the size in bytes.

Actually, the stat page referenced above has a fully done script ready to be picked up:
<?
function dir_size($dir)
{
$handle = opendir($dir);

while ($file = readdir($handle)) {
if ($file!= '..' && $file!= '.' &&!is_dir($dir.'/'.$file)) {
$mas += filesize($dir.'/'.$file);
} else if (is_dir($dir.'/'.$file) && $file!= '..' && $file!= '.') {
$mas += dir_size($dir.'/'.$file);
}
}
return $mas;
}
echo dir_size('DIRECTORIO').' Bytes';
?>

Here's what I use.

function directory_size($dir)
/* Return the file size for files in directory
Inputs:
$dirThe directory to check
Outputs:
The total file size of all files in $dir
*/
{
$retval = 0;
$dirhandle = opendir($dir);
while ($file = readdir($dirhandle))
{
if ($file!="." && $file!="..")
{
if (is_dir($dir."/".$file))
{
$retval = $retval + directory_size($dir."/".$file);
}
else
{
$retval = $retval + filesize($dir."/".$file);
}
}
}
closedir($dirhandle);
return $retval;
}
