So far, I found that it may be the fastest calculation method
Is there a faster one?
  1. date_default_timezone_set('UTC');
  3. function format_bytes($size)
  4. {
  5. $arr = array(' B', ' KB', ' MB', ' GB', ' TB ');
  6. for ($f = 0; $size >= 1024 && $f < 4; $f++)
  7. {
  8. $size /= 1024;
  9. }
  10. return round($size, 2).$arr [$f];
  11. }
  12. echo format_bytes('123456789');
  13. ?>
