Just make $item a 2-dimensional array, with the first diemnsion addressed by
$count; so:
$item[$count][] = $_POST['phone'];
$item[$count][] = $_POST['category'];
$item[$count][] = $_POST['copy'];
$item[$count][] = $_POST['pic_style'];
$item[$count][] = $cost;
$item[$count][] = $image;
$count += 1;
$item[$count][] = ...;
$item[$count][] = ...;
// etc.
Incorporating the (good) advice to use $_SESSION, this becomes:
$_SESSION['item'][$count][] = $_POST['phone'];
$_SESSION['item'][$count][] = $_POST['category'];
$_SESSION['item'][$count][] = $_POST['copy'];
$_SESSION['item'][$count][] = $_POST['pic_style'];
$_SESSION['item'][$count][] = $cost;
$_SESSION['item'][$count][] = $image;
$count += 1;
$_SESSION['item'][$count][] = ...;
$_SESSION['item'][$count][] = ...;
// etc.
Personally, I'd be inclined to use string indexes that indicate what's in each
element, to avoid having to remember somehow which numeric index corresponds to
which attribute; so:
$_SESSION['item'][$count]['phone'] = $_POST['phone'];
$_SESSION['item'][$count]['category'] = $_POST['category'];
$_SESSION['item'][$count]['copy'] = $_POST['copy'];
$_SESSION['item'][$count]['pic_style'] = $_POST['pic_style'];
$_SESSION['item'][$count]['cost'] = $cost;
$_SESSION['item'][$count]['image'] = $image;
$count += 1;
$_SESSION['item'][$count]['phone'] = ...;
$_SESSION['item'][$count]['category'] = ...;
// etc.
HTH
