This is confusing syntax although its operation is defined and it does "work". I would seek a better, more clear formulation. Also of course using $return is not the best choice of a name, use $accounts_validated or some other more descriptive term that describes the boolean nature of the return value.

Updated: Corrected the spelling of "formulation". Also, I would think that a very clear statement of what the $return value is, resolves the problems that ikegami points out. They can happen. I would not use side effects of an operator as a substitute for explicitly saying what you mean in a very clear way. The fact that we are even discussing what does "!!$return mean?", means that it shouldn't be used. It is confusing. And in my mind that is reason enough not to do it. Use some kind of "if", perhaps a ternary statement to resolve this down to an obvious boolean, $flag_all_ok, if necessary. Have the return statement return an obvious thing.
