How can I display the string with the sentence?

I've tried several things and I am stuck with this task for three days now. How can I display the string with the sentence or did I misunderstand the task (not native English)? Thanks for help.

index.php 
<?php

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

$fullname="$firstName $lastName";

This is wrong because variables are not strings. They do not need quotes around them since the $variables already are going to output strings. You will need to concatenation to have more than 1 variable like this.

$fullname=$firstName . $lastName;

and this part needs fixing up too ( you would need to uncomment it aka get rid of the double slash in the front )

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

and do not forget your semi-colon at the end of the statement.

echo $fullname;

Variables will be expanded within double quoted strings in php so there was nothing wrong with $fullname = "$firstName $lastName";

If you reassign to $fullname the entire sentence then task 2 is no longer going to pass because it's expecting the $fullname variable to only have the first and last name in it.

You have to either echo out the sentence directly or you could probably assign the sentence to a different variable and then echo out that variable.

thanks a lot. now I have code this:

$firstName="Rasmus"; $lastName="Lerdorf"; $fullname=$firstName . " " . $lastName; $fullname=$fullname . ' was the original creatot of PHP' . "\n"; echo $fullname;

The output in workspaces looks fine, but in the Challenge Task it says: Ooops! It looks like Task 2 is no longer passing. How can that be?

Hi Kristijan,

As mentioned in my other comment, you can't change the value of the $fullname variable.

Instead you can echo out the sentence directly without first assigning to a variable.

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

Another issue you had with your original code is that you had a space before the newline. This would have resulted in another error message since it wasn't specifically asked for in the instructions.
