Composer dont work on php 8

[matrix543]

Composer fail if you run php 8.05

Problem 1

• furqansiddiqui/erc20-php[0.1.4, ..., 0.1.x-dev] require furqansiddiqui/ethereum-rpc ^0.1.5 -> satisfiable by furqansiddiqui/ethereum-rpc[0.1.5].
• furqansiddiqui/ethereum-rpc 0.1.5 requires php ^7.1.0 -> your php version (8.0.5) does not satisfy that requirement.
• Root composer.json requires furqansiddiqui/erc20-php ^0.1.4 -> satisfiable by furqansiddiqui/erc20-php[0.1.4, 0.1.x-dev].

I have this problem too. You can install it with --ignore-platform-reqs

[matrix543]

I did a solution where I fork the repo edited it to work with php8 uploaded it so I could install the package with composer from my own repo

[matrix543]

composer require matrix543/erc20-php

@matrix543 How to get balance of token with this package? Can you give me example?

[matrix543]

i did it in laravel so install wih composer v2

in your laravel controller

use EthereumRPC\EthereumRPC; use ERC20\ERC20;

public static function getbalance($address){
    $id = Auth::id();

    $geth = new EthereumRPC('127.0.0.1', '8545');
    $token_contract = <ETH token contract addr>

    $erc20 = new ERC20($geth);

    $token = $erc20->token($token_contract);
    $balance = $token->balanceOf($address);

    return $balance;

}

in composer json

"matrix543/erc20-php": "^0.1.4", "matrix543/ethereum-rpc": "^0.1.5",

Does it work with metamask open nodes?

[matrix543]

it talks to a geth node that you run on your lokal pc or a vps you can connect metamask to a lokal geth node to

[aliqasemzadeh]

I want to use metamask RPCs to get balance of address in php without running full node.

[matrix543]

it depends if metamask let you connect to an ip and port the php package will work otherwise you have to run geth with lightmode on a server so it dosent eat up your hard drive

geth --syncmode "light"
