replace while loop with foreach


PHP doesn't have a mysql_fetch function that delivers all rows at once which could be used in a foreach look.

Try to get all rows in one loop and build an array with all rows. Then, iterate over this array and perform operations as you described.

How to use conditional in List.ForEach()?
The most naïve way: myList.Where(x => !itemsToRemove.Contains(x)) // LINQ extension method .ToList() <---- .ForEach(x => Session.Remove(x)); // List<T> method so this is required | Also you can use this: mystList.Except(itemsToRemove) .ToList() .ForEach(x => Session.Remove(x));
