"PHP Stupidity"

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/

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.

LINK

Not that it really matters, but wouldn't it be better practice to do...

echo('LINK');

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.
