How can I call a non static method into a static method in php?

Question

I completely new to PHP. I have done something this:

 class Foo  
 {         
    @BeforeSuite
    public static function prePare()
   {           
       $obj = new Foo;
       $obj->iVisit("https://google.com");
     }
  }

 public function iVisit($url)
   {
      if ($url != null) {
            $this -> getSession() -> visit($url);
         }
      else {
           throw new PendingException();
         }
   }
}

But it is throwing this error:

PHP Fatal error: Call to a member function getSession() on a non-object

Edited:

My scenario is to load a URL before other test cases start to run. So I choose to load the url in the @beforesuite function, but in behat, @beforesuite is a static function. I had to call the iVisit method from the static function.

Is there any other solution for this problem?

Its not a php concept, its just a programming concept.

You cannot just call a non static method anywhere, simply because you need to make an instance (or refer to a already present instance ) of that class to call the function.
