# JSON-RPC for PHP


## Overview

This package allows you to create and evaluate JSON-RPC messages, using your own
PHP code to evaluate the requests.

This package allows you to create and evaluate any JSON-RPC message. It
implements the JSON-RPC specifications, but does *not* provide a transport
layer—which you'll also need if you want to send or receive messages over a
distance! One of the beautiful features of JSON-RPC is that you can use *any*
transport layer to carry your messages: This package gives you that option.

If you're looking for an end-to-end solution, with the transport layer included,
then you should use one of these alternative packages instead:
* To send messages over HTTP(S), use the
[php-json-rpc-http](https://github.com/datto/php-json-rpc-http) package.
* To send messages over SSH, use the
[php-json-rpc-ssh](https://github.com/datto/php-json-rpc-ssh) package.


## Features

* Correct: fully compliant with the [JSON-RPC 2.0 specifications](http://www.jsonrpc.org/specification) (100% unit-test coverage)
* Flexible: you can use your own code to evaluate the JSON-RPC method strings
* Minimalistic: extremely lightweight
* Ready to use, with working examples


## Examples

### Client

```php
$client = new Client();

$client->query(1, 'add', array(1, 2));

$message = $client->encode();

// message: {"jsonrpc":"2.0","method":"add","params":[1,2],"id":1}
```

### Server

```php
$api = new Api();

$server = new Server($api);

$reply = $server->reply($message);

// reply: {"jsonrpc":"2.0","result":3,"id":1}
```

*See the [examples](https://github.com/datto/php-json-rpc/tree/master/examples) folder for full working examples.*


## Requirements

* PHP >= 7.0
