How to pass data into a class method's scope?

Hello I am trying to convert the value of an array to a variable.

I have a class named X as follows:

class x
{
    public static function getData()
    {
        $data = array(
            "start" => '$id',
            "end" => '$name'
        );
        return $data;
    }
}

The getData() method returns the array:

array (size=2)   
    'start' => string '$id' (length=3)
    'end' => string '$name' (length=5)

I have function as follows in another class:

$id = 10;
$name = "kheshav";    
$data = x::getData();
var_dump($data);

What I want is to resolve the $id and $name values in the array to its corresponding variable, so that end result will be as follows:

array (size=2)   
    'start' => int 10   
    'end' => string 'kheshav' (length=7)

I tried the following code but with no hope:

foreach ($data as $key => $value) {
    $data[$key] = eval("\$value =\"$value\";");
}

Well the conventional way to do this would be to pass the data into the function:

class x{

    public static function getData($id,$name){
        $data = array(
             "start" => $id,
             "end" => $name
        );
        return $data;
    }

}


$id=10;
$name = "kheshav";    
$data = x::getData($id,$name);
