如何将下面这段java代码的生成签名部分用PHP重写？

现在在用的方法不行和java生成的不一样（同样的json串），如果回答和下面的方法一样就不用回答了
：
//生成签名
private function generateSign($request){
$content = json_encode($request);
$privateKey = file_get_contents($this->sslKeyPath);
//var_dump($privateKey);
$key = openssl_get_privatekey($privateKey);
openssl_sign($content, $signature, $key, OPENSSL_ALGO_SHA256);
openssl_free_key($key);
$sign = base64_encode($signature);
return $sign;
}
参考文档：https://antchain.antgroup.com/docs/11/256485#h3-url-3
注：上述地址有java的sdk源码可供参考，REST json 串可以是：
{"data":{"name":"pruduct-liangfang-001","remark":"this is a test data"},"appId":"2088002286496263","version":"V_3_6_1","timestamp":1666162726318}
timestamp：可以写固定值：1666162726318
地址是请求地址：https://tschain.cloud.alipay.com/trace/merchant/register
私钥文本是：
