title: Calling non-static method with double-colon(::)
body: <p>Why can't I use a method non-static with the syntax of the methods static(class::method) ? Is it some kind of configuration issue?</p>
  
  <pre><code>class Teste {
  
      public function fun1() {
          echo 'fun1';
      }
      public static function fun2() {
          echo "static fun2" ;
      }
  }
  
  Teste::fun1(); // why?
  Teste::fun2(); //ok - is a static method
  </code></pre>
