# Msgpack for PHP
[![Build Status](https://github.com/msgpack/msgpack-php/workflows/ci/badge.svg?branch=master)](https://github.com/msgpack/msgpack-php/actions?query=workflow%3Aci+branch%3Amaster)

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
- PHP 7.0 +

## Install

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

```shell
pecl install msgpack
```

### Compile Msgpack from source

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

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

### Advanced Example
```php
<?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
<?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;
}

```
