Yes, you can use variable variables, like others have suggested, but why
not just use an array? Almost every implementation of variable-variables
seems to be a work around that's used instead of arrays.
Where are all of your $where variables coming from? If they are from a
form, just name them as "where[]", then simply loop through them using
foreach($_POST['where']) and check them all. This makes your code more
dynamic as you can add/subtract "where[]" elements and your "processing"
code doesn't change. With a variable-variable solution, you have to
change the number of loops you run each time to change the number of
"where" elements you have.
