Here there's my function used for writing size in human format :)
I think it's lighter than the one written above.
function humansize($size) {
$n = 0;
while (($size > 1024) and ($n < 3)) {
$size /= 1024;
$n++;
}
if ($size - floor($size) == 0)
$size = (int) $size;
else
$size = round($size,2);
switch ($n) {
case 0:
return $size."B";
break;
case 1:
return $size."KB";
break;
case 2:
return $size."MB";
break;
default:
return $size."GB";
break;
}
}
and if you are looking for a function that calculates the size of a directory, including all
subdirectories and files, look at this:
function dirsize($dir) {
$dh = opendir($dir);
$size = 0;
while (($file = readdir($dh)) !== false)
if ($file != "." and $file != "..") {
$path = $dir."/".$file;
if (is_dir($path))
$size += dirsize($path);
elseif (is_file($path))
$size += filesize($path);
}
closedir($dh);
return $size;
}
Let's enjoy them !
