Please tell me what I’m doing wrong?

I’ve been working on this for a minute

index.php 
<?php
//Place your code below this comment
$firstName ="Rasmus";
$lastName = "Lerdorf";
$fullName = $firstName + $lastName;
echo "$fullName was the original creator of PHP.\n";
?>

The plus operator in PHP means add and doesn't concatenate, you will need to use the full stop as the concatenate operator. Then as suggested above you'll need to add a space using ' ' an then another full stop after it.

In js the plus sign is used to concatenate :)

it does cause confusion when going from one language to the next, but in php unless you are not working with numbers then use the full stop :) Plus for maths lol

First, have you tried running your code locally or in a workspace or even something like http://phpfiddle.org/.

I'm not sure of the exact expected output from the challenge but the first thing I would double check is your concatenation operator.

Not sure why the second task is accepted but there is a space between first name and last name

$fullName = $firstName  . ' '. $lastName;
