Re: [PHP] Client side fatal PHP error From: Andrew Brampton (andrew <email protected>)

because the way && is evaluated.

if the first part of the && expression is false, then it doesn't even
attempt to look at the second part, meaning you get a fastest evaluation
:)...

I think its called Lazy Logic or something, I know its in the PHP Manual
somewhere :)
