MakeNiceSize

This is the php function, i use to create user friendly file size strings:

function MakeNiceSize($bytes, $mode="auto"){
  $suffix = array("B","KB","MB","GB","TB","PB","EB");
  $run = 0;
  
  if ($mode=="auto"){
    while ($bytes>=1024){
      $bytes /=1024;
      $run += 1;
    }
    return round($bytes,2)." ".$suffix[$run];
  }elseif($mode!="auto"){
    If (array_search($mode, $suffix)!==false){
      while ($suffix[$run]!=$mode){
        $bytes /=1024;
        $run += 1;
      }
    }else{
      return false;
    }
    return round($bytes,2)." ".$suffix[$run];
  }
}

Example:

echo MakeNiceSize(1024);
echo MakeNiceSize(1024,"auto");
echo MakeNiceSize(1024,"KB");

All three calls will return "1 KB"
