Yii version 2.0.15.1

You should pass arguments separately instead of using array.

$redis->eval($lua, "data1", "date2", 1, 1, time(), 2);

[alu12138]

Fail. Redis::eval() expects at most 3 parameters, 7 given

[alu12138]

这个问题是，yii2-redis执行命令有一个判断，mb_strlen()统计参数字数，数组作为参数将会报错。不知道该怎么兼容。
The problem is that the yii2-redis execution command has a judgment, mb_strlen() counts the number of arguments, and the array as an argument will report an error. I don't know how to be compatible.

Can you show fill stack trace of this error?

Redis->eval('\r\nlocal hongbao...', 'data1', 'date2', 1, 1, 1533642811, 2)

What is Redis? There is no such class in this extension.
