可以按照声明中定义的不同顺序传递php函数参数 [英] can php function parameters be passed in different order as defined in declaration

问题描述

假设我有一个函数/方法F()，它接受3个参数$ A，$ B和$ C定义.

Suppose I have a function/method F() that takes 3 parameters $A, $B and $C defined as this.

function F($A,$B,$C){
  ...
}

假设我不想遵循传递参数的命令，我可以这样打吗?

Suppose I don't want to follow the order to pass the parameters, instead can I make a call like this?

F($C=3,$A=1,$B=1);

代替

F(1,2,3)

推荐答案

绝对不是.

您可以传递无序参数的一种方法是采用关联数组:

One way you'd be able to pass in unordered arguments is to take in an associative array:

function F($params) {
   if(!is_array($params)) return false;
   //do something with $params['A'], etc...
}

然后您可以像这样调用它:

You could then invoke it like this:

F(array('C' => 3, 'A' => 1, 'B' => 1));
