Global variables of function inside function of a class

class Someclass{

    function topFunction()
    {       

        function makeMeGlobal($var)
        {
            global $a, $b;

            $a = "a".$var;
            $b = "b".$var;
        }

        makeMeGlobal(1);    
        echo "$a <br>";
        echo "$b <br>";

        makeMeGlobal(2);    
        echo "$a <br>";
        echo "$b <br>";
    }
}

I am using that test code on codeigniter but nothings happen.

I suppose to print a result like this 

a1
b1
a2
b2

How to handle those functions inside a class?

you are creating the global variables inside the function, try creating them in the class scope rather than the function. that should work.

You declare globals inside function scope.

Try to declare them at class scope:

class Someclass{

    function topFunction()
    {       

        function makeMeGlobal($var)
        {
            global $a, $b;

            $this->a = "a".$var;
            $this->b = "b".$var;
        }

        makeMeGlobal(1);    
        echo $this->a . "<br>";
        echo $this->b . " <br>";

        makeMeGlobal(2);    
        echo $this->a . "<br>";
        echo $this->b . "<br>";
    }
}
