Related to the question Verb conjugator for French, I was asked an question on whether one could summarize all the $exceptionIs<NAME_OF_EXCEPTION> = $exceptionmodel-> getValue() === ExceptionModel::NAME_OF_EXCEPTION lines. In other words, can one make dynamic variables out of the comparison of a value combined with all values of an enum?
