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).
