在PHP中使用多个参数的同名命名函数 [英] Same named function with multiple arguments in PHP

问题描述

我开始使用Java进行OOP，现在我对PHP很感兴趣。是否有可能用Java中的不同参数创建多个函数？或者，这种语言的解释/非类型性质会阻止这种情况并导致冲突？解析方案

其他人都有很好的代码解释。以下是更高级别的解释：Java支持方法重载，这就是您所指的当你用相同的名称但不同的参数讨论函数时。由于PHP是一种动态类型的语言，这是不可能的。相反，PHP支持默认参数，您可以使用它获得相同的效果。

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?

解决方案

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.
