⚡️ Web3 PHP is a supercharged PHP API client that allows you to interact with a generic Ethereum RPC.

I would like to extend the Eth class to implement eth_call for example, but I am unable to do so because the class is final. The same applies to Web3 or even Http (I had to add Content-type into headers for my BSC RPC to work)

        $request = new Request('POST', $this->url, [
            "Content-Type" => "application/json",
        ], $body);

Could you consider removing the final keyword from them?

It is not enough to just check the first two characters to make sure a string is Hex. Therefore the characters of the rest of the string (substr($value, 2) we know that the first two characters are '0x' at this point) must represent hexadecimal digits ctype_xdigit(substr($value, 2)).

Description

• Adds blockNumber() method to Eth namespace

Notes

• My understanding of this method is that it returns quantity of recent block numbers seen by the client. From this perspective, method name is a bit confusing. What is your suggestion about changing to getblockNumbers()?

I am not an expert, i am having this trouble. First i created a composer.json:

{ "minimum-stability": "dev",

}

then, in visual code, from terminal, i wrote this command: "composer require web3-php/web3" and terminal thorw this:

And in folder, appear the composer.lock and vendor folder with a bunch of stuff installed.

Inside the vendor folder there is an autoload.php file, which has this code in it:

// autoload.php @generated by Composer

require_once DIR . '/composer/autoload_real.php';

return ComposerAutoloaderInit9f1c798e6bb2829771949001eeeee0c7::getLoader();

so i want to make a test, and add the following to the autoload.php file:

// autoload.php @generated by Composer

require_once DIR . '/composer/autoload_real.php';

return ComposerAutoloaderInit9f1c798e6bb2829771949001eeeee0c7::getLoader();

print ("test");

Then go to my browser, http://localhost/web3ppp/vendor/autoload.php and nothing happend:

but if i put the print ("test"); before the return line, the text "test" appear,

// autoload.php @generated by Composer

require_once DIR . '/composer/autoload_real.php';

print ("test");

return ComposerAutoloaderInit9f1c798e6bb2829771949001eeeee0c7::getLoader();

so there is something wrong with the return line, but i dont know what is wrong.

Im using xampp with php 8.0.6 on windows 10.

Can anyone tell me what im doing wrong?

Platform : windows 10 Php : 8.0.13 Geth : 1.10.14-stable

Trying to fetch eth accounts results in an invalid null $response passed to array_key_exists at src\Transporters\Http.php:55

Debuging the contents of the http response shows a string Invalid content type, only application/json is supported

Adding a content type to the request header fixes the issue

@nunomaduro Let me know if i can help fixing the issue and make a PR ! cheers,

Description

• Adds isMining() method under Eth namespace

Notes

I would love to be able to help on this project. I was able to make this contribution by looking at following things:

• Ethereum JSON-RPC Specification
• web3.js documentation

Can you please recommend some resources to look into for more effective contribution?

Thanks!

added dev-master for resolve this error:

[InvalidArgumentException]
  Could not find a version of package web3-php/web3 matching your minimum-stability (stable). Require it with an explicit version constraint allowing its desired stability.

We are not sure. Feel free to pull request documentation or code that clarifies that.

I use this Python tutorial to understand which stream to decode. https://medium.com/coinmonks/unlocking-the-secrets-of-an-ethereum-transaction-3a33991f696c

Also use some resources from this class https://github.com/CatAndPigeons/ethereum-adapter/blob/17b34c89976e1606904e64f97524280a8cf0ba50/src/Connector/EthereumRpcServiceTrait.php

So I created a Trait with a decodeInput method to decode ERC20 or BEP20 transfer transaction.

Thanks

Some clients always respond with invalid request headers, such as me and #22

I have fixed this problem and it has worked for me.

My client version is Geth/v1.10.14-stable-11a3a350/linux-amd64/go1.17.5

i want to ERC20 token balance with your module;

similar code for web3p;

$contract = new Contract($web3->provider, $string); $contract->at($contractAddress)->call('balanceOf', $address, function ($err, $account) use (&$balance) { if ($err !== null) { echo 'Error: ' . $err->getMessage(); return; } $balance=goThen($account); });
