You are absolutely right.
True = 1
False = 0
make an if statement, or echo ...

Subject: RE: [PHP] True || False ?
to take this a step further, PHP doesn't seem to have types at all try ...
echo 1 + true; // gives 2
echo 1 . true; // gives 11
true is a constant that seems to equate to 1, false is 0. Or is this just my
interpretation?
