Re: The constant use of isset()

Sean Coates a écrit :

So if the variable is set and contains "false", we can't check it ? And near same problem for 0, empty array and empty string.

How would you ever get false (the value, not the string) into a request variable? (without setting it that way after the request init, that is) So this isset() behavior will only be available for request variable, not for all variables ?

I can't do that ?     $a = isset($foo['bar'])
