List of JSON RPC client libraries in PHP available on GitHub.

https://github.com/fguillot/JsonRPC

• no transport injection (curl)
• no json options (json_encode, json_decode)
• no read timeout (no interface)
• returns raw result from result key and null on error
• id = mt_rand() (no way to set custom)

https://github.com/EvilScott/junior

• no transport injection (file_get_contents)
• no json options (json_encode, json_decode)
• no any timeout options
• response object with public props
• utf8_decode (wtf)
• id = uniqid() (no way to set custom)

https://github.com/soundasleep/jsonrpcclient/

• no transport injection (fopen)
• no json options (json_encode, json_decode)
• no any timeout options
• returns raw result from result key and throws exception on error
• id = ++ (no way to set custom)

https://github.com/marcelklehr/tivoka/

• no transport injection (file_get_contents for http, fsockopen for tcp and websocket)
• no json options (json_encode, json_decode)
• no read timeout
• public props
• id = uuid (no way to set custom)

https://github.com/sergeyfast/

• no transport injection (curl)
• no json options (json_encode, json_decode)
• no read timeout (no interface)
• id = ++ (no way to set custom)
• bad design at all

https://github.com/subutux/json-rpc2php

• too simple, no options, common problems as for others

https://github.com/johnstevenson/jsonrpc/

• transport injection! but no interface for it
• no json options (json_encode, json_decode)
• client contains response, doesn't return it
• id = ++ (no way to set custom)

https://github.com/Pozo/json-rpc-php/

• no transport injection (curl)
• no json options (json_encode, json_decode)
• no any timeout
• returns raw result as stdObject
• native interface (without alternative)
• id = ++ (no way to set custom)

What's the perfect JSON RPC client library

• separate implementation for JSON RPC objects and communication
• transport injection (interface) with out-of-the-box implementation for popular clients like Guzzle
• json options for json_encode, json_decode
• timeouts: connect, write, read
• uses objects for request and response, no public props — public getters
• request with custom id (id should be controlled by a request manager, not request itself)
• promises as results on batch request
