Format file size

val — Mon, 16 Aug 2010 12:29:51 +0000

Code snippet to output number of bytes with unknown capacity:

function format_filesize($bytes) { if ($bytes == 0) return '0.00 B';


    $s = array('B', 'Kb', 'MB', 'GB', 'TB', 'PB');

    $e = floor(log($bytes)/log(1024));

return sprintf('%.2f '.$s[$e], ($bytes/pow(1024, floor($e)))); }

I don’t know the author of this code.
