将php数组中的每个元素转换为函数的分离参数

Hie everyone am trying to pass the following array:

$cars=array("Volvo","BMW","Toyota"); 

To the following function

function foo(){
   $numargs = func_num_args();
   $args = func_get_args();
   print_r($args);
}

What I want is to make each element in array to be separated element in $args

at the same time I don't to write the function and parameters like that way

foo($cars[0],$cars[1]);

<?php

for ($i=0; $i<sizeof($array); $i++) {
 $c = $array[$i];
 foo($c);
}

?>

I'm completely sure what it is you are asking but here would be a simple solution: Change foo to:

function foo(){
   $args = func_get_args()[0];
}

$args will then contain the array of element you pass into foo() if you called it like this:

foo($cars);

In case you may be passing more than just the array parameter you would need to loop over the arguments and then could do something with each:

foo(){
   $args = func_get_args();
   while(!empty($args))
   {
      //do something with each argument. ie. print out it's value
      print_r(array_shift($args));
   }
}

Call it again by the same way: foo($cars);

It seems a little bit strange what you are trying to so though as I think you could just write you foo method as:

foo($array){
    foreach($array as $array_item)
    {
       // do something with each item ie. print out it's value
       print_r($array_item);
    }
}
