i have created a custom class to manage all types of session 

i have created few static methods but for unset its giving me an error

```
 public static function unsetSession($para) {

     return unset($_SESSION[$para]);

    }

```

Can nay one give an idea why its throwing error

I read php document 

**Description** 

```
void session_unset ( void )

```

The `session_unset()` function frees all session variables currently registered.

**Return Values** 

No value is returned.

is it unset is not returning ?

Thanks
