Fully unit-tested JSON-RPC 2.0 for PHP

6.0.0 2019-07-26 20:20 UTC



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:


  • Correct: fully compliant with the JSON-RPC 2.0 specifications (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



$client = new Client();

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

$message = $client->encode();

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


$api = new Api();

$server = new Server($api);

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

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

See the examples folder for full working examples.
