2,894 PointsI can't figure this assignment out
I'm stumped. I like "vanilla" Randy likes "cookie dough". I tried various combinations of: $flavor="vanilla" if $flavor="cookie dough" echo "Randy's favorite flavor is $flavor, also!"
thinking it would simply not echo. but I get an error message.

2,894 Pointsthe question I believe was that if I didn't like the same flavor as the instructor, I should list my flavor and if it did not match it should not display (echo) the last sentence that the instructor likes the same flavor.
so: $flavor="vanilla" if $flavor="cookie dough" echo "Randy's favorite flavor is $flavor, also!"
Petros below suggests I put in a double equal "==" so the last line reads:
if ($flavor == "cookie dough") echo "Randy's favorite flavor is "$flavor", also!"
I am not sure why he put a period before and after the variable. if you have some thoughts let me know.

For example, if $flavor="Vanilla", and the code is like this: echo "Randy's favourite flavour is $flavor, also!"; the output will be "Randy's favorite flavour is $flavor, also!"
If you write the code like this echo "Randy's favorite flavour is ".$flavor.", also!";, PHP will output "Randy's favorite flavour is ", then the value of the $flavor variable and finally the ", also!" string.
Here is a link to the php manual for this: http://www.php.net/manual/en/language.operators.string.php - it has quite a few examples.

16,181 PointsMake sure that when you assign a value to a variable you use a single '=' and when you compare values you use a double '==' sign.
The conditional as you wrote it in your post should be:
if ($flavor == "cookie dough") echo "Randy's favorite flavour is ".$flavor.", also!";

2,894 PointsThanks Petros. I am not clear why you put a dot "." before and after the variable. Is that necessary?
