README

The purpose of this project is to implement MessagePack serialization with PHP failover. This might be useful for someone unable to install php-modules, or using HipHop to compile PHP as C++.

Project

Please see: http://msgpack.org/

Example

  use CharStream;
  
  $hole = "Light"
  $pack = msgpack_pack($hole);
  
  if ( msgpack_unpage($pack) === $hole ) {
       echo "The hole is lit.";
  }

Caveats

Only msgpack_pack() and msgpack_unpack() are defined.
It's only tested on little endian architecture, but should work on big endian as well, please test it if able.
The uint64 and int64 types probably requires 64-bit systems to work
It uses is_x() to select the type, do your casts before using the functions
Unlike the official lib you can't pack objects. If you know how to do this please fork.
It will always pack integers into the least amount of bits possible, and will prefer unsigned.

Benchmark

Based on msgpack/php/benchmark.php

As you can see the pure PHP implementation (msgpack-php) is quite slow compared with the great php-extension msgpack has created. However when msgpack-php is compiled using HipHop (msgpack-hphp) the performance difference is much less, with msgpack-hphp even beating msgpack in this particular benchmark a few places, perhaps due to the fact that the benchmark itself is compiled with HipHop as well.

The timing values are average seconds sampled 10 times with 10.000 iterations each. Percentages are relative to normal php serialize() (not HipHop's version).
