The problem is that $e here is not being interpreted how I'd expect (I'd
assume it to be a number). Do I need to cast $e as an int or is there
something I'm missing?

$e will by of type string, since $ex is an array of strings, since it is the
result of an explode() of a string.
- either do an explicit typecast in case you are really sure, you will
always have numerical values in there (check it...)
- or rely on php to make an implicit typecast which _might_ work, but then
again which _might_ make problems and lead to unexpected results if you
have mixed values as keys in your array $foo.
