Joining strings together is called "concatenation", which was explored in detail in the video on Combining Strings. You may want to review that video.

The operator symbol for concatenation is a period ("."). It essentially acts like "glue" sticking two strings together to make one longer one. You can combine as many as you want in a single statement, and they can be a mix of literals (things in quotes) and variables containing strings.

I'll bet you can get it now, without an explicit "spoiler".

<?php
$firstName = 'Rasmus';
$lastName = 'Lerdorf';

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

Exactly as Steven Parker mentioned, but figured I would provide a demonstration of how you would specifically concatenate strings in PHP.
