human readable file size

Question

function humanFileSize($size)
{
    if ($size >= 1073741824) {
      $fileSize = round($size / 1024 / 1024 / 1024,1) . \'GB\';
    } elseif ($size >= 1048576)          


        

Answer 1

I'm using this method:

function byteConvert($bytes)
{
    if ($bytes == 0)
        return "0.00 B";

    $s = array('B', 'KB', 'MB', 'GB', 'TB', 'PB');
    $e = floor(log($bytes, 1024));

    return round($bytes/pow(1024, $e), 2).$s[$e];
}

works great in o(1).
