i got this error message when trying to display the sorting.php file from pg 69 chapter 2

Fatal error: Cannot use [] for reading in C:\Program Files\Apache Group\Apache2\htdocs\sorting.php on line 2

this is my code

<?php
$flavor[] - "blue raspberry";
$flavor[] = "root beer";
$flavor[] = "pineapple";

sort($flavor);
print_r($flavor);
?>

Please could some one tell me where i've gone wrong
thanks
