<?php foreach ($flavors as $flavor) { echo "<li>" . $flavor["name"] . " " . "+" . $flavor["likes"] . "</li>"; } ?> Why are we putting an empty quotes after the $flavor["name"], but the question said followed by space?
Please may you help, thank you!

In PHP, " " is actually counted as a space. "", would be counted as empty quotes. So:
echo "<li>" . $flavor["name"] . " " . "+" . $flavor["likes"] . "</li>"
This would write <li>Vanilla +312</li> as opposed to <li>Vanilla+312</li>. (The space is gone).

What you are doing is concatenating the value of those variables with a string containing a space.
Here is an example:
<?php
$first_name = "John";
$last_name = "Doe";
/*if you echo the concatenation of these 2 variables like this:*/
echo $first_name . $last_name;
/*
you get JohnDoe
You want a space between the names so you do it like so:
*/
echo $first_name . ' ' . $last_name;
?>
Hope this helps clear thigs up.
