Array to string conversion is the only way to get access to a useful string in PHP. We luck out that the conversion includes an uppercase A
, otherwise we may not be able to get uppercase letters without including other characters.

The only real way of generating these from alphabetic letters is to use binary operators like ^
. For example, we could take advantage of the fact that d^H==','
, h^H==' '
, and i^H=='!'
. This should make it possible to remove these three characters adding only the ^
operator.
