Project Overview :page_facing_up:

PHP RPC Lib is PHP lib for query http rpc used by substrate.

Overview

• PHP is an extremely common development language in the web field, and currently there is no RPC library for substrate. I have already developed https://github.com/gmajor-encrypt/php-scale-codec in the previous grant. PHP RPC Lib is necessary to interact with the chain

Project Details

• Sr 25519

Since PHP does not have an encryption library for sr25519

Will provide the following interfaces

1. SR25519.NewKeypairFromSeed(seed)
2. SR25519.sign(message),
3. SR25519.verify(message, signature)

• Send transaction

Example

$api = new SubstrateRpc("websocket_or_http_url");
$signer = new SubstrateRpc\Util\Keyring\Signer("privatekey");// or HD
$api->setSigner($signer);
$tx = $api->tx->balances->transfer("to_address", 10000);
$tx->signAndSend();

• Read/subscribe HTTP/Websocket to RPC endpoints

Example

$api = new SubstrateRpc("websocket_or_http_url");
$api->rpc->System->Heath();

# or read storage 
$api = new SubstrateRpc("websocket_or_http_url");
$api->rpc->state->System->Account("/ALICE");

• Support all substrate RPC method https://polkadot.js.org/docs/substrate/rpc

Ecosystem Fit

Can help php language developers to easily access the substrate (polkadot) ecology

Future Plans

1. Long-term support, Because I found that the underlying changes of the substrate are still very frequent, like metadata, I expect will be a long-term job in the future
