Re: [MLUG] PHP newbie

nods, No problem.
Yea, the (!$var) and ($var) thing also works in C.

I didn't know that by default it is off,
I just know it used to work for me, these days for me,
the whole CGI part for PHP is either disabled or enabled.
phpinfo() will show all of the varibles for CGI working in
PHP. But not in my scripts, or future scripts that I write.
I must have something in Apache or PHP enabled that breaks PHP's
CGI varibles.
