You might be making it more difficult than it needs to me. You're not
dealing with a huge number of queries here so why not just loop it? I would
simply loop through the $_SESSION array and query the dbase for each item.
foreach ($_SESSION as $key => $val)
{
$query = "SELECT * FROM inventory WHERE itemnumber = '$val'";
$result = mysql_query($query, $db);
// .. blah blah blah...
}

Subject: [PHP] mySQL Queries using PHP's SESSION variables
> Hello, I am stuck here. In the name of efficiency I want to lower the
number

user

> eg. : I want something like this:
>
> $result = mysql_query("SELECT * from Inventory where ItemNumber is in
> $HTTP_SESSION_VARS");
> // I need proper syntax to replace "is in"
>
> where Inventory has, ItemNumber (unique), Price, ItemName.
> So say the surfer has three items in the Session, then I stored the three
> unique ItemNumbers.
> Then with the above query I can get the rest of the information to
represent
> to the user.
> I am looking down the avenues of a Set datastyp or maybe Enum, but I don't
