I didn't see the context of the above comment, but <?php echo '"$uname"'; ?> does exactly what I'd expect it to do based on the above rules. It outputs the literal string "$uname" > And furthermore the solutions to one of my MySql query > problems being adding single quotes ' ' to all the variables. Yep. MySQL (and, in fact, just about any database) likes to have non-numeric values quoted in a query string. > Now by my understanding, thats not supposed to work. 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. So... <?php $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? --- Mark Roedel | "The most overlooked advantage to owning a Systems Programmer | computer is that if they foul up there's no LeTourneau University | law against whacking them around a little."
