$_SESSION[cart][$product_name] returns { Array[Bowl_in_Green_glaze] }

$_SESSION[cart][$product_name] returns { Array[Bowl_in_Green_glaze] }
Is there a Mid$ function and a Left$ function in PHP so I can trim off the first 8 and the last 3 characters?
(or is there a way to filter that intrinsically?)

Oh, and for the extra 9 points, why is this failing as "Fatal error: Unsupported operand types" ?
$total += ( $_SESSION['cart'][$product_name]['price'] * $count );
it also fails like this:
$total = $total + ( $_SESSION['cart'][$product_name]['price'] * $count );

Thanks,
David

// LEFT FUNCTION
function left($string, $length) {
      return substr($string, 0, $length);
}

// RIGHT FUNCTION
function right($string, $length) {
      return substr($string, strlen($string)-$length);
}

// FUNCTION TO CUT STRING FROM LEFT AND RIGHT
function cut_string($string, $chars_from_left, $chars_from_right) {
      return substr($string, $chars_from_left, strlen($string)-$chars_from_left-$chars_from_right);
}

// FOR YOUR SITUATION...
$s = cut_string ( $_SESSION[cart][$product_name], 8, 3);

Is there a Mid$ function in PHP?
This is an important part of the question.
I'm adding a few points for this clarification.
Thanks!
