if( USE_FULL_NAME == TRUE ) { $name = $first_name . '' . $last_name;
I cant figure out how to make the space between $first_name and $last_name, couldnt see what letters he typed in the video.
Now im using this: . '' .
But doesnt make a space

In PHP, you use the period (.) for combining several strings and values of variables. With three variables, it looks like this:
var $text1 = "Hello ";
var $space = " ";
var $text2 = "World";
echo $text1 . $space . $text2
The result will be "Hello world". Now that you want to echo a string in between two variables, you have to surround the string in quotation marks (either " like in my example or ' like in your code) just like in the following example:
var $text1 = "Hello ";
var $text2 = "World";
echo $text1 . " " . $text2
This way we get the same result without using a variable for the space.
If you are not sure what exactly is typed in the video, you can always download the project files and find the corresponding code there.

var $text1 = "Hello "; var $space = " "; var $text2 = "World"; echo $text1 . $space . $text2
If i wanna do this on 1 row? How would i write it if you use my code?

If you decide to use single quotation marks (') instead of the double ones ("), the second example will look like this:
var $text1 = 'Hello ';
var $text2 = 'World';
echo $text1 . ' ' . $text2
Beware that there still needs to be a space between the quotation marks.
