Re: Re[2]: [PHP-DEV] PHP 5.1

Personally, I doubt this is a problem.. I mean, how many ifsetor() variables are we talking here? You call the function, so therefor the variable could be set, otherwise you wouldn't be checking for it. In the case it was set, it would've been in the symbol table anyway.
