All methods use array parameters. What are the drawbacks of this method in project development? Php is a weak type language. in the project, if I define all the method portals as $ array, which of the following are the drawbacks of this function, such as functiontest ($ array ), it doesn't matter. it's just a form parameter ., I didn't see that framework was doing this. it doesn't mean that all the methods use array parameters. What are the drawbacks of doing so in project development?

------ Solution --------------------
It doesn't matter. it's just a form parameter.
------ Solution --------------------
I didn't see that the framework was doing this. it doesn't mean this is not the case.

A function (method) usually requires a set of specific parameters.
In addition, this set of parameters can be checked during compilation to check whether the number of parameters is sufficient.
When you pass the parameter as an array, you need to check the validity and completeness of the parameter in the function body.
We have to say Disadvantages. This should be considered
------ Solution --------------------
Let's see how your function is written. Your function test ($ array) parameter is not necessarily an array. it depends on what data is passed during the call.
------ Solution --------------------
Error message not defined for variable
The rest depends on how your function is written.

In addition to array, you can use 'XXX, xxx, xxx, XXX', and $ xxxx to pass the parameter, but it is not necessary to break the problem into an array and then change the function.

Discussion

If arrays are used as parameters, but the validity and completeness of parameters are not checked in the function body, what problems will arise?

------ Solution --------------------
How do you write it is your business. As for the validity of the parameter, you also write it in the program. Also, you must transfer the array to the program based on the actual situation, no. net, isn't it. net parameters are all arrays ??? No.
