How does the { } syntax work?
I think it looks better in a query then doing ' ". ." ' when I need to insert a superglobal.
I couldn't find it in the manual.

    Ok, thanks.
    Is there any difference between the two? speed wise or anything else?

      Using braces involves variable interpolation, so it is slightly slower than concatenation.

        Thanks, thats what I thought.
