php array error

Recommended Posts

i keep getting this error when there is no array.

 

Warning: array_values() [function.array-values]: The argument should be an array in /home/learnat2/public_html/cart.php on line 37

 

but i put this code to prevent the error

 $items = $_SESSION['items'];

if(is_array($items)) {
$quantity = array_count_values($items);
$items    = array_unique($items);
}

 

i still get the error. it should not display an error because $items is not an array, no values have been added.
