Re: if(($var && $var < $othervar) || (statement like first) || ( other statement))

I can see how you are confused, let me try to clear things up: $a = 1; $b = 2; if ($a && $a < $b) { } What that is saying is "if $a is unequal to zero and $a is less then $b". The expression: "if ($a && $a) {" would mean "if $a is greater than zero and $a is greater than zero". Basically the following two things are identical: 1. if ($a) 2. if ($a != 0) { It is just a short hand way of doing it.
