I didn't see the context of the above comment, but

        <?php echo '"$uname"'; ?>

does exactly what I'd expect it to do based on the above rules.  It
outputs the literal string

Yep.  MySQL (and, in fact, just about any database) likes to have
non-numeric values quoted in a query string.

Here, I think, is where we can clear things up for you a bit by
explaining that the important quotes, the ones that determine which of
the two behaviors you listed will apply, are the *outermost* ones.


                $var1 = "cookies";
                $var2 = "milk";

                echo "$var1"; // outputs: cookies
                echo '$var2'; // outputs: $var2
                echo "I like '$var1'"; // outputs: I like 'cookies'
                echo '"$var2"'; // outputs: "$var2"
                echo "'Got $var2?'"; // outputs: 'Got milk?'

Get the idea?
