php也可以调用web3相关接口进行转账交易，唯一需要注册的就是 infura ，获得一个密钥，然后就可以调用了，首先：
composer require web3p/web3.php@0.2.1
composer require blockchainethdev/ethereum-tx下面示例在php 7.3.33版本运行正常测试通过，其他版本请自行测试是否能用。
下面是一些简单的示例：
<?php
require('vendor/autoload.php');
use Web3\Web3;
use Web3\Contract;
use Web3\Providers\HttpProvider;
use Web3\RequestManagers\HttpRequestManager;
use Blockchainethdev\EthereumTx\Transaction;
