Pass parameters based on conditions

In PHP, passing parameters based on conditions is a common programming technique, which allows us to flexibly pass parameters to functions or methods according to different situations. By passing parameters conditionally, we can dynamically change the behavior or results of the function according to different needs. This technique is very useful in actual development and can improve code reusability and flexibility. Next, PHP editor Xiaoxin will introduce in detail how to pass parameters according to conditions in PHP.

Question content

I have a function that accepts variable parameters.

func MyFunc(strs ...string)
MyFunc(entry1, entry2, entry3)

My use case is to pass one of the entries based on some conditions.

Is it possible to have a similar effect like below (so that I don't need to call MyFunc 's if-else in both):

MyFunc(entry1, if(condition)entry2, entry3)

Solution

Just prepare the parameters as slices:

myArgs := []string{"entry1"}
if (condition) {
    myArgs = append(myArgs, "entry2")
}
myArgs = append(myArgs, "entry3")

Then call the variadic function with your slice:

MyFunc(myArgs...)
