global variables & classes

Hi ... I'm new to php, and I have a little problem : I declare an array in the main body of my script, I define a class which includes a function from where I would like to reffer to this array ... but I can't manage to access it :( Here is the code used : <? $priorities = array( 1 => "very low", 2 => "low", 3 => "normal", 4 => "high", 5 => "very high", ); // my array // class task { // ... // function display() // one of the class member functions //

    {
       echo $priorities(3); // does not echo anything :( //
    }

} $test = new task; $test->display(); ?> Thanks for help. John.
