PHP RPC Lib Follow up
Project Overview 📄​
Overview​
As Gavin mentioned in this CoinDesk article, WebAssembly is the future of smart contracts.
However, WebAssembly, as the main Smart Contract in the substrate ecosystem, lacks the necessary infrastructure. Except for the lib of contracts provided by polkadot.js, there are no more third parties that can query the contract storage and interact with the package.
PHP is one of the most popular development languages in the world, PHP is used by 77.8% of all the websites whose server-side programming language(https://w3techs.com/technologies/details/pl-php).
Traditional PHP Website developers will lack the necessary SDK if they come into contact with the substrate, However, the lack of support for contracts in the current php-substrate-api makes it very difficult to use PHP as a development language to interact with the substrate.
Therefore, this proposal is an extension of php-substrate-api to improve the practicability of this package further and increase support for smart contracts.
Project Details​
-
Abi encode & decode, support contract metadata v0,v1,v2,v3,v4, this will be used to read and write smart contracts
-
Deploy wasm smart contract
Example
$api = new SubstrateRpc("websocket_or_http_url");
$api->rpc->contracts->new("wasm_code", "gas limit","value");
- Read contract values
Example
$api = new SubstrateRpc("websocket_or_http_url");
$api->rpc->contracts->balanceOf("from","contract");
- Send Contract transaction
Example
$api = new SubstrateRpc("websocket_or_http_url");
$signer = new SubstrateRpc\Util\Keyring\Signer("privatekey");// or HD
$api->setSigner($signer);
$tx = $api->tx->contracts->transfer("to_address", 10000);
$tx->signAndSend();
Ecosystem Fit​
CIt can help PHP language developers easily access the substrate (polkadot) ecology

Future Plans​
This milestone still lacks support for smart contract verification, there is no better solution at present, and will be supported after research
