I’m using Laravel and trying to work with Solana block chain
When I try to generate a wallet address I got the address right but the private key is not formatted correctly
This is my function below

public function generateWallet() { 
    try { 
        // Initialize the curve and generator 
        $adapter = EccFactory::getAdapter(); $generator = EccFactory::getNistCurves()->generator256();

        // Generate private key
        $privateKey = $generator->createPrivateKey();

        // Generate public key
        $publicKey = $privateKey->getPublicKey();

        // Serialize keys to DER format
        $privateKeySerializer = new DerPrivateKeySerializer($adapter);
        $publicKeySerializer = new DerPublicKeySerializer();

        $privateKeyDer = $privateKeySerializer->serialize($privateKey);
        $publicKeyDer = $publicKeySerializer->serialize($publicKey);

        // Base58 encode the 32-byte public key
        $publicKeyBytes = str_pad(gmp_export($publicKey->getPoint()->getX()), 32, "",     STR_PAD_LEFT);
        $base58 = new Base58();
        $walletAddress = $base58->encode($publicKeyBytes);
        return [
            'private_key' => bin2hex($privateKeyDer),
            'public_key' => bin2hex($publicKeyDer),
            'address' => $walletAddress
        ];
    } catch (Throwable $th) {
        return [$th->getMessage()];
    }
}

I want to get a correct private key which I can then use it to connect a wallet, send transactions and stuff like this

I tried to ask chatgpt but no helpful answer
