在类的静态函数内调用函数

Question

In laravel framework i often use - Model::find($id)->orderedBy(param);

I would like to know how to achieve such expression. I began with this:

 Class Test
 {
    static public function write()
    {
       echo "text no 1";

       function second()
       {
          echo "text no 2";
       }
     }
 }

now i when i do

Test::write();

i get "text no 1"

what i want is to do:

Test::write()->second();

and get " text no 2"

Unfortunately my way doesn't work.

Is it possible ?

Excuse me for bad language - still learning.

Model::find($id)->orderedBy(param) just means that static method find returns object, who's method orderBy is then executed.

Example:

Class Test1
{
    public function say_hello()
    {
        echo 'Hello!';
    }
}

Class Test2
{
    static public function write()
    {
        $obj = new Test1();
        return $obj;
    }
}

Test2::write()->say_hello();
