Tools for working with the CBOR data format in PHP

composer require firehed/cbor

Note: Only decoding is supporing at this time

$decoder = new Firehed\CBOR\Decoder();

$binaryString = "\x18\x64"; // CBOR for int(100)
$data = $decoder->decode($binaryString);

// OR
$byteArray = [24, 100];
$data = $decoder->decodeArrayOfBytes($byteArray);

There is currently very limited support for tagged types. When an unsupported tag is encountered, an OutOfBoundsException will be thrown.
