将未定义数量的参数转发给另一个函数 [英] Forward undefined number of arguments to another function

问题描述

我将用一个接受任意数量函数的简单函数来解释这个问题

I will explain the question with a simple function accepting any number of function

function abc() {
   $args = func_get_args();
   //Now lets use the first parameter in something...... In this case a simple echo
   echo $args[0];
   //Lets remove this first parameter 
   unset($args[0]); 

   //Now I want to send the remaining arguments to different function, in the same way as it received
   .. . ...... BUT NO IDEA HOW TO . ..................

   //tried doing something like this, for a work around
   $newargs = implode(",", $args); 
   //Call Another Function
   anotherFUnction($newargs); //This function is however a constructor function of a class
   // ^ This is regarded as one arguments, not mutliple arguments....

}

我希望问题现在已经清楚了，针对这种情况有什么解决办法?

I hope the question is clear now, what is the work around for this situation?

我忘了提到我调用的下一个函数是另一个类的构造函数类.类似的东西

I forgot to mention that the next function I am calling is a constructor class of another class. Something like

$newclass = new class($newarguments);

推荐答案

用于简单的函数调用

使用call_user_func_array，但不要内爆 args，只需将剩余的 args 数组传递给 call_user_func_array

use call_user_func_array, but do not implode the args, just pass the array of remaining args to call_user_func_array

call_user_func_array('anotherFunction', $args);

用于创建对象

使用:ReflectionClass::newInstanceArgs

$refClass = new ReflectionClass('yourClassName');
$obj = $refClass->newInstanceArgs($yourConstructorArgs);

或:ReflectionClass::newinstance

$refClass = new ReflectionClass('yourClassName');
$obj = call_user_func_array(array($refClass, 'newInstance'), $yourConstructorArgs);
