谁能帮我把这段JAVA语言改成php的, 或者告诉我是什么意思.非常感谢?

Question

public static String getMacStr(VerifyRequest verifyRequest, String macKey){
 StringBuilder allInputAreaParams = new StringBuilder();
 allInputAreaParams.append(verifyRequest.getVersionId());
 allInputAreaParams.append(verifyRequest.getChrSet());
 String allInputAreaParamsStr = allInputAreaParams.toString();
 String md5SourceText = allInputAreaParamsStr + macKey;
 System.out.println(DigestUtils.md5Hex(md5SourceText));
 return DigestUtils.md5Hex(md5SourceText);
}

Answer 1

就是把后面几个字符串拼接做md5加密。versionId, chrSet, macKey

Answer 2

class VerifyRequest{

private $versionId;
private $chrSet;

public function getVersionId(){
    return $this->$versionId;
}
public function getChrSet(){
    return $this->$chrSet;
}

}

static function getMacStr($verifyRequest,$macKey){

$allInputAreaParams = $verifyRequest->getVersionId().$verifyRequest->getMacStr();
$md5SourceText = $allInputAreaParams.$macKey;
return md5($md5SourceText);

}

就是一个hash的算法而已

Answer 3

所有参数加上macKey 之后md5 加密
