Not quite, for a couple of reasons.  As Salvatore pointed out, 
getArray() is a function, not a variable, so you need to code it as a 
function.  The other problem is you never called makeArray() and don't 
have a constructor, so $my_array doesn't exist (also it should be 
declared as a class variable).

Something like this should works:

class MyClass {
   private $my_array;

   public function __construct() { // Constructor
     $this->my_array = array('Mon', 'Tues', 'Wed', 'Thurs', 'Friday',
       'Sat', 'Sun');
   }
   public function getArray($i) {
     if ($i >= 0 && $i < count($this->my_array))  // Verify index
       return $this->my_array[$i];
     else
       return null;  // Out of range
   }
}

$myVar = new MyClass();
$mydate = $myVar->getArray(1); // Pass index as an argument
echo $mydate;

=> Tues

(PHP array indexes start with zero, not one).
