I agree, it's not a bug, just a different design or interpretation of the statement. I further agree that the programmer should put parentheses around statements if visually ambiguous. Also, from left to right seems more logical. That it happens in this particular case that the result seems counter-intuitive doesn't mean it is illogical. I just had trouble understanding at first why it would output 'two' instead of 'one' when the contents of the variable clearly was 1. A different construct could be used better used in a case where a variable can have more than 2 values. elseif or even a switch, though more verbose, is probably much more readable. Sorry, Robert, for the huge font. I was sure I had reduced it before sending in gmail... Copy/paste from the website made it that big. I raised the issue also to get a better understanding what other php programmers think and I much better understand some things now.
