echo "Randy's favorite flavor of ice cream is ____.";


1 Answer

If I remember correctly this was a test on concatenation. so the question wanted you to echo, or print to the screen the favorite flavor stored in the variable. so basically it should look something like this:


echo "Randy's favorite flavor of ice cream is" . $flavor . ".";

so to recap, in php we use the period "." character as the concatenation operator. which basically appends any variable that needs to be processed to the string. So since the variable needs to come after "is" and before the period"." to end the statement, we place a concatenation operator "." before and after $flavor. Anything that's considered a string in the echo statement needs to be wrapped in quotation marks to signify its a string. That's why at the end of that statement, the period is wrapped in quotation marks.

If we just wanted to end the statement with the flavor and not the period it would look like this:


echo "Randy's favorite flavor of ice cream is" . $flavor;

since there are no more string characters coming after $flavor, we can end the statement with the semi-colon. Hope this helps. I know there is more to this question, but this is all you presented, if you posted the question along with this code bit, I could probably help a little further.
