Library for work with binary data and objects

Simple library for work with binary data and objects in PHP. See the examples below for more information, or check out Encoder, Decoder, Serializer, Byter and Ascii.

Coder

namespace PetrKnap\Binary;

$data = base64_decode('hmlpFnFwbchsoQARSibVpfbWVfuwAHLbGxjFl9eC8fiGaWkWcXBtyGyhABFKJtWl9tZV+7AActsbGMWX14Lx+A==');
$encoded = Binary::encode($data)->checksum()->zlib()->base64(urlSafe: true)->data;
$decoded = Binary::decode($encoded)->base64()->zlib()->checksum()->data;

printf('Data was coded into `%s` %s.', $encoded, $decoded === $data ? 'successfully' : 'unsuccessfully');

Serializer

namespace PetrKnap\Binary;

$data = [
    'type' => 'image/png',
    'data' => base64_decode('iVBORw0KGgoAAAANSUhEUgAAAAEAAAABCAYAAAAfFcSJAAAAAXNSR0IArs4c6QAAAA1JREFUGFdj+L+U4T8ABu8CpCYJ1DQAAAAASUVORK5CYII='),
];
$serialized = Binary::serialize($data);
$unserialized = Binary::unserialize($serialized);

printf('Data was serialized into `%s` %s.', base64_encode($serialized), $unserialized === $data ? 'successfully' : 'unsuccessfully');

Self-serializer

namespace PetrKnap\Binary;

class DataObject implements Serializer\SelfSerializerInterface
{
    use Serializer\SelfSerializerTrait;
    
    public function __construct(
        public string $data,
    ) {
        $this->referencesToConstructorArgs = [
            &$this->data,
        ];
    }
}

$instance = new DataObject('Lorem ipsum dolor sit amet, consectetur adipiscing elit.');
$instance->data .= ' Duis venenatis ultricies elementum.';
$binary = $instance->toBinary();
$binaryFromHelper = Binary::asBinary($instance);

printf(
    'Data object was serialized into `%s` %s.',
    base64_encode($binary),
    $binary === $binaryFromHelper && $instance == DataObject::fromBinary($binary) ? 'successfully' : 'unsuccessfully',
);

Byter

namespace PetrKnap\Binary;

$data = base64_decode('hmlpFnFwbchsoQARSibVpfbWVfuwAHLbGxjFl9eC8fiGaWkWcXBtyGyhABFKJtWl9tZV+7AActsbGMWX14Lx+A==');
$sha1 = sha1($data, binary: true);
$md5 = md5($data, binary: true);
$unbitten = Binary::unbite($sha1, $md5, $data);
[$sha1Bite, $md5Bite, $dataBite] = Binary::bite($unbitten, 20, 16);

printf(
    'Hashes and data was unbitten into `%s` %s.',
    base64_encode($unbitten),
    $sha1Bite === $sha1 && $md5Bite === $md5 && $dataBite === $data ? 'successfully' : 'unsuccessfully',
);

ASCII

namespace PetrKnap\Binary;

printf(Ascii::RecordSeparator->join(
    Ascii::UnitSeparator->join('200', 'EUR', 'Maya Wilson'),
    Ascii::UnitSeparator->join('1600', 'USD', 'Quinton Rice'),
));
