PHP中具有多个参数的相同命名函数

Question

I started off OOP with Java, and now I'm getting pretty heavy into PHP. Is it possible to create multiples of a function with different arguments like in Java? Or will the interpreted / untyped nature of the language prevent this and cause conflicts?

Answer 1

Everyone else has answers with good code explanations. Here is an explanation in more high level terms: Java supports Method overloading which is what you are referring to when you talk about function with the same name but different arguments. Since PHP is a dynamically typed language, this is not possible. Instead PHP supports Default arguments which you can use to get much the same effect.
