PHP

Stuck on concatenation. Code works on PHPFiddle but not in the PHP track exercise.

So, I am trying to do the task which gets the output "Rasmus Lerdorf was the original creator of PHP" with a new line break.

I put together the code below. When I run it in PHP Fiddle it works fine, yet when I create it in the actual exercise workspace, it tells me I'm not using the $fullname variable.

Any thoughts anyone. I've tried writing it a few different ways and it always returns the same issue. I can't see what's wrong.

<?php $firstName = "Rasmus"; $lastName = "Lerdorf"; $fullname = "$firstName" . " $lastName"; $output = $fullname . " was the original creator of PHP\n"; echo $output; ?>

At a quick glance it looks ok, but I would clean up some of the concatenations. Not sure if it will work, but worth a try. Also $fullName might need a capital 'N'. The code challenges can be finicky....

$fullName = $firstName . " " . $lastName;

OR LIKE

$fullName = "$firstName $lastName";

Hope that helps!

Hi Zachary,

As you say, code challenges can be finicky. I first used "$fullName" based on all the previous video talk of using capitals on the second word. However, in the code challenge text they actually write it as "$fullname".....annoying huh! Tell me one thing, then do something different! This little baby took me almost 20mins to work out why it was saying I wasn't using the variable.

Anyways, "$fullname" is correct. Also, from your amended version of my code, I assumed it would be missing a space between the first and last name, but that's not the case at all so thanks :).

So I checked the final code again and thought to myself "what if I remove the $output variable step and just echo $fullname". Sure enough this works and I pass. So the correct code I needed was:

<?php $firstName = "Rasmus"; $lastName = "Lerdorf"; $fullname = "$firstName" . " $lastName"; echo $fullname . " was the original creator of PHP\n"; ?>

Thanks for your help Zachery :)
