#CBOR encoder for PHP

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.

Installation

Add 2tvenom/cborencode as a requirement to composer.json:

{
    "require": {
       "2tvenom/cborencode": "dev-master"
    }
}

Usage

<?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);

Compatibility

Checked with Ruby extension in encode and decode

Known issues

  • Not support tags. 6 major type (in future)
  • Not support 16 and 32 floats encoding (maybe in future)
  • All floats will be serialized only as IEEE 754 Double-Precision Float (64 bits follow)
  • Encode does't support indefinite-length values.
