Note Submitter: pdontthink at angrynerds NO*SPAM dot com ---- This is similar to the dirsize functions above except it adds: - Take into account directories that you don't have permission to open (nasty results otherwise) - Catch errors and return -1 (remember to check for this!) - Don't follow symlinks (I'm implementing a quota system, so users shouldn't be responsible for contents of symlinked directories): You can call it like this: $size = dirsize('some/dir/path'); if ($size < 0) echo 'ERROR! Bad path!'; else echo 'Your dirsize is ' . format_size($size); And the relevant functions are: // returns the total size, in bytes, of all files // contained in the directory tree beginning at the // specified directory // returns -1 if any problem occured (such as if the // directory given was nonexistent) // function dirsize($directory) { if (!is_dir($directory)) return -1; $size = 0; if ($DIR = opendir($directory)) { while (($dirfile = readdir($DIR)) !== false) { if (is_link($directory . '/' . $dirfile) || $dirfile == '.' || $dirfile == '..') continue; if (is_file($directory . '/' . $dirfile)) $size += filesize($directory . '/' . $dirfile); else if (is_dir($directory . '/' . $dirfile)) { $dirSize = dirsize($directory . '/' . $dirfile); if ($dirSize >= 0) $size += $dirSize; else return -1; } } closedir($DIR); } return $size; } // stolen from another fine user on php.net // function format_size($rawSize) { if ($rawSize / 1048576 > 1) return round($rawSize/1048576, 1) . 'MB'; else if ($rawSize / 1024 > 1) return round($rawSize/1024, 1) . 'KB'; else return round($rawSize, 1) . 'bytes'; }
