使用

Create a transaction:

$from = Ethereum\Types\Buffer::hex('34c76cfdb9ed59f4e1e4e61fa27f97f90412d81b');
$to = Ethereum\Types\Buffer::hex('744d70fdbe2ba4cf95131626614a1763df805b9e');

$nonce = Ethereum\Types\Buffer::hex('2e');
$value = Ethereum\Types\Buffer::int(0);
//因为每个代币可以规定自己的小数位, 所以实际的转账值=数值 * 10^小数位

//0x095ea7b3代表某个代币的转账方法hex(transfer) + 对方的转账地址hex + 转账的值的hex
$data = Ethereum\Types\Buffer::hex('095ea7b300000000000000000000000039a23012c065e0a93a6e268717c8b0f25f0430e90000000000000000000000000000000000000000000000000000000000000000');
$gasPrice = Ethereum\Types\Buffer::hex('033428f000');
var_dump($gasPrice);
$gasLimit = Ethereum\Types\Buffer::hex('02350c');
//$pk = Ethereum\Types\Buffer::hex('Set private key in PHP_ETH_RAW_TX_PK env var');
if (!$pk) {
    exit("/!\ Set private key in PHP_ETH_RAW_TX_PK env var" . PHP_EOL);
}

$chainId = Ethereum\Types\Buffer::int(1); // rinkeby
var_dump($chainId);
$tx = new Ethereum\Transaction(
    $from,
    $to,
    $value,
    $data,
    $nonce,
    $gasPrice,
    $gasLimit
);

Sign a transaction:

$raw = $tx->sign($pk, $chainId);

echo "Generated raw transaction :" . PHP_EOL;
echo $raw->getHex() . PHP_EOL;
