Information-size and transfer-rate value objects.

The package contains:

• Byte for data sizes stored internally as bytes
• ByteUnit and InformationUnit enums for unit metadata
• BitRate for transfer rates stored internally as bits per second
• BitRateUnit for bit/byte-per-second labels and conversion factors

Installation

composer require componenta/byte

This package is standalone.

Byte Usage

use Componenta\Stdlib\Byte;

$size = Byte::mb(1.5);

(string) $size;        // "1.5 MB"
$size->toBits();       // 12582912.0
$size->to('kB', 2);    // formatted string
$size->getValue('MB'); // numeric value in megabytes

Byte accepts numeric values and human-readable strings:

$a = Byte::fromHumanReadable('10 MB');
$b = Byte::fromBits(8_000);
$c = Byte::from(2, 'GB');

Byte Operations

Byte supports:

• comparison: compare, equalTo, lessThan, greaterThan, range checks
• arithmetic: increment, decrement, multiply, divide, modulo, abs
• aggregation: sum, average, maximum, minimum
• transfer estimates: getTransferTime, getFormattedTransferTime

Range generation is capped internally to avoid accidental huge allocations.

Bit Rate Usage

use Componenta\Stdlib\BitRate;
use Componenta\Stdlib\Byte;

$rate = BitRate::mbps(80);

$seconds = Byte::mb(10)->getTransferTime($rate);
$amount = $rate->calculateTransferAmount(1);

BitRate supports both bit and byte transfer units:

BitRate::fromHumanReadable('80 Mbps');
BitRate::fromHumanReadable('10 MBps');
BitRate::kilobytesPerSecond(512);

Unit Rules

• Byte uses binary storage units based on 1024.
• BitRate uses decimal transfer units based on 1000.
• BitRate stores its internal value as bits per second.
• Mbps and MBps are different labels: megabits per second vs megabytes per second.

Serialization

BitRate implements JsonSerializable. Byte implements Stringable and exposes explicit conversion methods for numeric values and formatted strings.
