Grr.
I'm sure I'm being ridiculously stupid, but say I define varaible $name to Alex, then want to link to root.com/$name.
Now, what I think I should be doing is simple: LINK
What's wrong? Why doesn't it work?
I keep getting unexpected T_string etc... I know I'm missing something, but what?

Short syntax:
http://root.com/
http://root.com/
Oh right. Makes a lot of sense now...
Cheers :D.

It's the concatenation operator in PHP.
You use it to join two strings together, or to add one string to another, e.g:
$var = "foo";
$var .= "bar";
echo $var; // Would print: foobar
The + sign is used to add two numbers together, e.g.:
$var = 2+3;
echo $var; // Would print: 5
or similarly as above:
$var = 2;
$var += 3;
echo $var; // Would print: 5

What does the "." do?

Well, actually, it would be better practice to define $rootname and have echo($rootname).
Nyah. :D
But actually, if I were to want to echo or print two variables would I write echo('$var1''$var2')? Or 'var1'+'var2' ?

No.
It's actually better to make less use of the echo statement, keeping HTML outside of php sections.

There's nothing wrong with that and it works fine when I just tested your exact code.
Usually that error means that you haven't put a semicolon or closing bracket on the line before, therefore it doesn't expect an echo statement.
