Php Calling the functions of same class one after another

I want to write something like (laravel uses):

View::make('FooBarView')->with('foo', $foo)
                        ->with('bar', $bar);

My knowledge and imagination made me to use new self instances. But I don't think that this is the best idea around and I could not handle it.

Google couldn't help me because of my bad keywords I think. I don't want to make you write code for me for sure but what is the name of this design pattern or whatever?

In laravel's source, with function uses 

return $this;

But how to use it after make?

By the way, in this example; with method helps you to set variables for view's render.

To call what the function returns, the function will have to return something that is possible to call.

In this case, you could for example return "this":

class View {
  /** 
  * @returns View
  */
  public static function make($foo) { 
    /* do stuff, return new View instance */ 
    return new View();
  }
  /** 
  * @returns View
  */
  public function with($foo, $bar){
    /* do stuff */
    return $this;
  }
}

That way, whenever you call with you will get the class instance back, which in turn will be callable:

 View::make("foo")->with("foo")->with("bar");
 // Will be same as:
 $v = View::make("foo");
 $v = $v->with("foo");
 $v = $v->with("bar");
