It'll suppress warnings and errors. If the $purchitem does not have a
key 4 or 5, like in your example, then you'll get a warning for
undefined offset, depending on your error reporting level. This just
suppresses that. 

If you do it this way, you may want to sort $purchitem if you can't
guarantee it's going to be in ascending order. Or you can use in_array()
and not care about the order.
