I cloned dev branch into public html and installed dependencies through composer. I want to to use this project to interact with my php7 website and a go-ethereum node running on amazon linux ec2-instance. I can interact with that using geth console and curl function in the terminal.

When I run ethereum-php/public/client-example.php, I get below error in browser. I have my node up and running at 127.0.0.1:8545. I tried with 127.0.0.1 instead if localhost also. But same error. Please help.

We have a problem:

I want to interact with that node from my browser to create wallet public addresses for each user and do transactions and get wallet balance. Are these functions possible with this plugin.?

Regarding eth_syncing()
The main problem is that Ethereum has multiple return types (Bool/Array) varying dependend on the client. I need to have a deeper look how to work around that. We might create a custom Data type for that.

ethereum-php/src/JsonRpcInterface.php

Line 120 in 9c8a748

public function eth_syncing(): EthB;

The Error is triggered because the return value is wrongly Boolean, while it should be

ethereum-php/resources/ethjs-schema.json

Line 11 in 9c8a748

"eth_syncing": [[], "B|EthSyncing"],

from my browser to create wallet public addresses

This is currently not in my scope, as I don't want to recommend unlocked Ethereum Nodes. But you are welcome to join. Please PM me if you want to discuss.

do transactions and get wallet balance

Currently working on calling TX. But my focus is first non-payable calls. But the way how it is designed I should work with an unlocked geth/parity and payable calls too.

eth_syncing() needs a wrapper to include the Boolean and the status.
