请问 getData('transferFrom', $params); 里面的$params参数要怎么传入？

我运行以下代码的结果是 由$ownerAddress账号转移原生代币到$toAddress，而不是由$fromAddress转移指定代币到$toAddress。
请问想要实现 由$fromAddress转移指定代币到$toAddress要怎么写？

$fromAddress已经授权了$ownerAddress指定代币
运行以下代码结果为交易类型为EVM转账而没有执行合约调用

<?php
$ownerAddress = '';
$ownerPrivateKey = '';

$fromAddress = '';
$toAddress = '';
$amount = '1';

$web3 = new Web3('https://exchainrpc.okex.org/');
$eth = $web3->getEth();

$nonce = 0;
$eth->getTransactionCount($ownerAddress, function ($err, $count) use (&$nonce) {
	if ($err !== null) {
		throw new Exception($err->getMessage());
	}
	$nonce = $count;
});

$contract = new Contract($eth->getProvider(), $abi);
$contractInstance = $contract->at('0xaa27badaa3c9ec9081b8f6c9cdd2bf375f143780');

// 函数数据
$functionData  = $contractInstance->getData('transferFrom', $fromAddress, $toAddress, $amount);
$rawTx  = [
	'nonce' => '0x' . $nonce->toHex(),
	'from' => $ownerAddress,
	'to' => $toAddress,
	'value' => '0x0',
	'gas' => '0x' . $estimatedGas->toHex(),
	'gasPrice' => '0x' . $gasPrice->toHex(),
	'chainId' => 1,
	'data' => '0x' . $functionData
];
$transaction = new Transaction($rawTx);

// 离线签名
$signedTransaction = $transaction->sign($ownerPrivateKey);

// 广播交易
$transactionHash = '';
$eth->sendRawTransaction('0x' . $signedTransaction, function ($err, $tx) use (&$transactionHash) {
    if ($err !== null) {
        throw new Exception($err->getMessage());
    }
    $transactionHash = $tx;
});

echo $transactionHash;

问题已经解决，将$rawTx里的to设置为合约地址，执行就是触发合约了。
