推荐答案

array_combine 如果作为参数给出的数组中的值数量不同，则返回 FALSE .这可能是为什么您收到关于不受支持的操作数类型的错误的原因-您正在尝试将布尔值与数组结合在一起.

array_combine returns FALSE if number of values in arrays given as arguments is different. That's probably a reason why you're getting an error about unsupported operand types - you're trying to combine a boolean with an array.
