A simple library for converting byte sizes with PHP 5.3+

#Nomnom
Get it? Bytes? Bites?
Nomnom handles file size conversion for PHP 5.3+. It handles both binary (base 2) and metric (base 10) conversions. It provides a simple interface for converting between sizes of any similar base!
A Nomnom object is constructed with a "start" value that will be converted.
Two methods are defined on this object: from
and to
. Each of these methods takes
a metric or binary unit to convert from/to.
The to
method takes an optional precision
value to specify how many significant
digits to keep in the result.
$nomnom = new Nomnom(1440000);
//metric conversion to 1.44
$mb = $nomnom->from('B')->to('MB', 2);
$nomnom = new Nomnom(1024);
//binary conversion to 1
$kb = $nomnom->from('KiB')->to('MiB');
//convert a file size
$filesize = new Filesize('/path/to/file.txt');
$mb = $filesize->to('MB');
As a convenience, Nomnom provides a factory method called nom
and constants for the metric
and binary units.
//returns 1.44
Nomnom::nom(1440000)->from(Nomnom::BYTES)->to(Nomnom::MB, 2);
//factory for Filesize
Nomnom::file('/path/to/file.txt')->to(Nomnom::MB);
'B' refers to bytes in either base 10 or base 2.
Nomnom will throw a ConversionException
if the from
and to
methods contain units
for different bases, i.e no $nomnom->from('KiB')->to('MB');
Nomnom requires the bcmath extension to handle greater precision.
