Having trouble adding space to the string.

I have reviewed the videos and did some searching online and cannot find how to add these two strings together and add space. What am I missing?

index.php 
<?php

//Place your code below this comment
$firstName = 'Rasmus';
$lastName = 'Lerdorf';
$fullName = "$firstName" + "$lastName";

?>

Try using PHP concatination like this:

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

This:

. ' ' .

concatinates the two variables and adds one space character to the string.

It is still giving me an error and saying I did not add a space between first and last name. This course is frustrating because the code challenges often cover material not referenced in the videos.

Looking at your original code, do this:

  1. remove the quotation marks as these are unnecessary. so: $fullName = $firstName + $lastName;
  2. remove the + character as this is a mathematical operator and the variables are strings. so: $fullName = $firstName $lastName;
  3. add the concatination. so: $fullName = $firstName . '' . $lastName;
  4. add a space character between the concatination. so: $fullName = $firstName . ' ' . $lastName; When I run this last code snippet in the challenge is passes.

Going through it again it passed. I appreciate your help.
