Is it possible to send transaction in Binance Smart Chain using web3.php and web3p/ethereum-tx?

[VIKASKO]

I am trying to send BEP-20 tokens from one address to another. I am getting the following error while attempting to sign the transaction with Privatekey. "Uncaught InvalidArgumentException: The input type didn't support" at this line of code $signedTransaction = $ethereumTx->sign($privateKey);

Here is the full code :

`
require 'web3.php/vendor/autoload.php';
require 'ethereum_tx/autoload.php';

use Web3\Web3;
use Web3\Contract;
use Web3\Utils;
use Web3p\EthereumTx\Transaction;

$web3 = new Web3('https://bsc-dataseed.binance.org/'); // Use the BSC node URL

// Replace with the actual contract address and ABI
$contractAddress = '0x55d398326f99059fF775485246999027B3197955';
$recipientAddress='0x7Affe1A120843E41b271E577900F0B5c43c2C2d9';

$tokenDecimals = 18; // Replace with the actual token's decimal places
$amount = 1; // Replace with the actual amount you want to transfer

$amountInBaseUnits = $amount * (10 ** $tokenDecimals);

$contractABI = "contract ABI";

// Set your wallet's private key
$privateKey = "myprivatekey";

$eth = $web3->eth;

// Create an instance of the contract using the ABI and address
$contract = new Contract($web3->provider, $contractABI, $contractAddress);

$transferFunctionCall = $contract->at($contractAddress)->getData(
'transfer', // Function name
$recipientAddress, // Parameter 1
$amountInBaseUnits // Parameter 2
);

// Fetch the nonce asynchronously
$web3->eth->getTransactionCount('0x02e6deD21C6c46CC4FFF2991988af13069C7c2A3', function ($err, $nonce) use ($web3, $contractAddress, $transferFunctionCall, $privateKey) {
if ($err !== null) {
echo "Error fetching nonce: " . $err->getMessage();
} else {
// Construct the transaction
$transaction = [
'from' => '0x02e6deD21C6c46CC4FFF2991988af13069C7c2A3',
'to' => $contractAddress,
'gas' => '0x' . dechex(100000), // Replace with appropriate gas value
'data' => $transferFunctionCall,
'nonce' => $nonce
];

	$ethereumTx = new Transaction($transaction);

$signedTransaction = $ethereumTx->sign($privateKey);

    // Send the transaction with a callback function
    $web3->eth->sendRawTransaction('0x' . $signedTransaction->getHex(), function ($err, $txHash) {
        if ($err !== null) {
            echo "Error sending transaction: " . $err->getMessage();
        } else {
            echo "Transaction Hash: " . $txHash;
        }
    });
}

});

var_dump($transactionHash);
