GitHub - Netlift/CBOREncode: PHP CBOR encoder/decoder

Decoder/encoder from PHP data to CBOR binary string. This code has been developed and maintained by Ven at January 2014.

CBOR is an object representation format defined by the IETF. The specification has recently been approved as an IETF Standards-Track specification and has been published as RFC 7049.

<?php
include("vendor/autoload.php");

//target for encode
$target = array(true, array("variable1" => 100000, "variable2" => "Hello, World!", "Hello!"), 0.234, 0, null, 590834290589032580);

//encoded string
$encoded_data = \CBOR\CBOREncoder::encode($target);

//debug info output
$byte_arr = unpack("C*", $encoded_data);

echo "Byte hex map = " . implode(" ", array_map(function($byte){
        return "0x" . strtoupper(dechex($byte));
    }, $byte_arr)) . PHP_EOL;

echo "Byte dec map = " . implode(" ", $byte_arr) . PHP_EOL;

//decode
$decoded_variable = \CBOR\CBOREncoder::decode($encoded_data);
//output
var_dump($decoded_variable);
