PHP函数的无限参数?

2022-01-21 00:00:00 function arguments php

在 php 中如何创建一个可以接受无限数量参数的函数:myFunc($p1, $p2, $p3, $p4, $p5...);

In php how would you create a function that could take an unlimited number of parameters: myFunc($p1, $p2, $p3, $p4, $p5...);

我的下一个问题是:如何将它们传递给另一个函数,例如

My next question is: how would you pass them into another function something like

function myFunc($params){
  anotherFunc($params);
}

anotherFunc 会像使用 anotherFunc($p1, $p2, $p3, $p4, $p5...) 调用它一样接收它们

推荐答案

call_user_func_array('anotherFunc', func_get_args());

func_get_args 返回一个数组,其中包含传递给调用它的函数的所有参数,并且 call_user_func_array 调用给定函数,并传递给它一个参数数组.

func_get_args returns an array containing all arguments passed to the function it was called from, and call_user_func_array calls a given function, passing it an array of arguments.
