newbie: a very simple question (I hope)

I am trying some excercises in a book and one of the excercises says to: Assign values to two variables. Use comparison operators to test whether the first value is: 1. the same as the second 2. less than the second 3. Print the result of each test to the browser. My question is, how do I print the result? For example, say I use the following expression: $x = 3; ++$x < 4; // false print $x; I know how to print out the value of $x, but not the test result of 'true or false'.
