Courses Plus Student 499 PointsGroundhog's Day scenario in PHP Development
when I change the code I've created in Task 4 everything is great until I confirm it and then it tell me that my code in Task 3 is no longer valid. I'm in an insane loop of going back changing Task 3 to be correct, altering it for Task for to be correct and then getting a message telling me Task 3 is no longer correct.
HELP!!! Somebody!

Courses Plus Student 94,610 PointsHi Eric,
I went through the challenge again and I typed in your values. After staring at it for a while I realized that in task 3 you dropped the <p> tag around Randy's message.
I believe it still passed task 3 because the if statement is false at that point and the string never gets echoed. So the code checker probably isn't looking at that string.
In task 4 it does get echoed and the code checker is probably noticing that it's not wrapped in p tags.

Courses Plus Student 499 PointsHere's the code in order:
Task 3 <?php $flavor = "chocolate"; echo "<p>Your favorite flavor of ice cream is "; echo "$flavor"; echo ".</p>"; if ($flavor == "cookie dough") {echo "Randy's favorite flavor is cookie dough, also!";}
?>
This is the code for Task for that works in preview
Task 4 <?php $flavor = "chocolate"; echo "<p>Your favorite flavor of ice cream is "; echo "$flavor"; echo ".</p>"; if ($flavor == "cookie dough") {echo "Randy's favorite flavor is cookie dough, also!";}
?>
when I hit check code I get the following error message: Oops! It looks like Task 3 is no longer passing.

Eric Cyrs
Courses Plus Student 499 PointsOK I thought it would be better if I took screen shots of the lesson so everyone can see what happening, exactly. Rod, you are absolutely right. The code I pasted here in the forum was in error but that isn't the code I've been using (my mistake). I've actually been using the correct code.
Below is a link of a page I created on my website with screenshots (in order) of what's happening.

Let me know if you find anything wonky with the code in those screen shots.
Thanks for taking the time to review this! I mean it is really driving me nuts.

11,935 PointsHi Eric, Look at line 4: echo "$flavor"; I don't think echoing the content of a variable should require quotes. See what happens if you remove them.
Jason Anello
Courses Plus Student 94,610 PointsHi Rod,
It turns out there's a difference between using single and double quotes. With double quotes, the variable would be evaluated. With single quotes, it would echo the string "$flavor". So you would see your variable name on the page and not its contents.
So double quotes around the variable will successfully pass task 2. It should pass without too.
There's some good info here about the 4 ways to specify strings in php for anyone interested:

Courses Plus Student 94,610 PointsYou're welcome.
It never ends, and it feels overwhelming at times. In this industry, we'll never be done with learning. The technology changes too rapidly.
Eric Cyrs
Courses Plus Student 499 PointsJason, you're absolutely right! I'm learning a valuable lesson. Having had a "little" coding experience is a dangerous thing. I removed the <p></p> tags for some unknown reason, not sure why I did that, but when I placed them back in the code worked.
I really appreciate the responses from both you and Rod. I'm scratching my head right now trying to think of what led me to make such a bonehead decision. Hmmm....

Courses Plus Student 94,610 PointsCan you post the code that you're using to pass task 3 and then the code you are writing in task 4 which causes task 3 to no longer pass?
