从数组创建变量并使用它们来调用方法而不知道变量名称PHP

Question

I have a factory pattern like this:

public function ViewFactory implements Factory {
    public function __construct() {

    }

    public static function Create($params) {
        //does not return variables, only extracts them
        $p = extract($params, EXTR_PREFIX_ALL, "var_");

        //return object of view and pass in all variables extracted from array
        return new View($p);
    }

    ***
    ***
}

interface Factory {
   public function Create($params);
   ***
   ***
}

Im trying to use extract but it does not return variables I just have to access them using keys from associative array prefixed by var_. Is it possible to somehow return all values of array as variables comma separated and pass it into function?

My View Class:

class View {
   public function __construct($path, $parameters, $site_title) {
         ***
   };
}

I'm not quite sure if this is what you are asking for, but you can use ReflectionClass::newInstanceArgs to create an instance of a class and pass it arguments from an array :

public static function Create($params) {
    $class = new ReflectionClass('View');
    return $class->newInstanceArgs($params);
}
