php可变参数可以取得具体的参数名称吗

比如:

function test($data,...$params){
    var_dump($params);
}
$data = ['test'=>'test'];
$a = 1;
$b = 2;
$c = 3
test($data,$a,$b,$c);

现在打印出来的是

array(3) { [0]=> int(1) [1]=> int(2) [2]=> int(3) }

有什么办法可以取得参数名吗?变成下面这种

array(3) { ['a']=> int(1) ['b']=> int(2) ['c']=> int(3) }

php 层面上 应该是不可以的,将对应值赋值给变量,然后变量传递给形参,此时和变量名是没有关系的
