Msgpack for PHP

Build Status

This extension provides an API for communicating with MessagePack serialization.

MessagePack is a binary-based efficient object serialization library. It enables to exchange structured objects between many languages just like JSON. But unlike JSON, it is very fast and small.

Requirement

Install

Install from PECL

Msgpack is a PECL extension, thus you can simply install it by:

pecl install msgpack

Compile Msgpack from source

/path/to/phpize
./configure --with-php-config=/path/to/php-config
make && make install

Example

<?php
$data = array(0 => 1, 1 => 2, 2 => 3);
$msg = msgpack_pack($data);
$data = msgpack_unpack($msg);

Advanced Example

<?php
$data = array(0 => 1, 1 => 2, 2 => 3);
$packer = new \MessagePack(false);
// ^ same as $packer->setOption(\MessagePack::OPT_PHPONLY, false);
$packed = $packer->pack($data);

$unpacker = new \MessagePackUnpacker(false);
// ^ same as $unpacker->setOption(\MessagePack::OPT_PHPONLY, false);
$unpacker->feed($packed);
$unpacker->execute();
$unpacked = $unpacker->data();
$unpacker->reset();

Advanced Streaming Example

<?php
$data1 = array(0 => 1, 1 => 2, 2 => 3);
$data2 = array("a" => 1, "b" => 2, "c" => 3);

$packer = new \MessagePack(false);
$packed1 = $packer->pack($data1);
$packed2 = $packer->pack($data2);

$unpacker = new \MessagePackUnpacker(false);
$buffer = "";
$nread = 0;

//Simulating streaming data :)
$buffer .= $packed1;
$buffer .= $packed2;

while(true) {
   if($unpacker->execute($buffer, $nread)) {
       $msg = $unpacker->data();

       var_dump($msg);

       $unpacker->reset();
       $buffer = substr($buffer, $nread);
       $nread = 0;
       if(!empty($buffer)) {
            continue;
       }
   }
   break;
}
