PHP boolean testing question

I have a question about testing for Boolean values in PHP. Assume that the $server variable contains the string "localhost".

The strpos() function documentation says it "Returns the position of the first occurrence of a string inside another string, or FALSE if the string is not found. Note: String positions start at 0, and not 1."

Can someone show me how you would test the strpos() function whether or not the substring was found? Because I've tried:

            if (strpos($server, "boo") == FALSE) {
                echo "Substring was NOT found<br/>";
            }
            else {
                echo "Substring was found<br/>";
            }

But whether I set the substring to "boo" or "localhost", it doesn't seem to make a difference. Thanks.
