In the last challenge...

Hi, for whatever reason the "Get Help" button is disabled in the "String Manipulation" challenge, so that is why I'm asking this here:

I pass stage one and two with no problems but when I append to the variable in stage three I get an error saying that stage two no longer passes. Thus I can't complete the challenge.

The code works in workspaces and in the preview button available in the challenge:

<?php

//Place your code below this comment
$firstName = 'Rasmus';
$lastName = 'Lerdorf';
$fullname = $firstName . ' ' . $lastName;
$fullname .= ' was the original creator of PHP' . "\n";
echo $fullname;
?>

output:

Rasmus Lerdorf was the original creator of PHP

Hi there! In your first code, you are overwriting the $fullname variable which is what is causing the challenge to fail. I'm of the opinion that your second code should work, and probably does but the challenge does not ask you to create a new variable. Here's what I used:

<?php

//Place your code below this comment
$firstName = 'Rasmus';
$lastName = 'Lerdorf';
$fullname = $firstName . ' ' . $lastName;
echo "$fullname was the original creator of PHP\n";
?>

Hope this helps! :sparkles:

The alternative fails as well. The error says "...You did NOT use the $fullname variable"

<?php

//Place your code below this comment
$firstName = 'Rasmus';
$lastName = 'Lerdorf';
$fullname = $firstName . ' ' . $lastName;
$newline = $fullname . ' was the original creator of PHP' . "\n";
echo $newline;
?>

Here is the working solution: 

<?php

$firstName = 'Rasmus';
$lastName = 'Lerdorf';

$fullname = "$firstName $lastName";

echo $fullname . ' was the original creator of PHP' . "\n";

?>
