Show code. In particular:

echo 'key = $x';
and echo "key = $x';

are *NOT* the same thing.

Um, what does this mean?

Do you mean you have something like:
$v = 'Up your $x with a $x';
(note: no substitution is done here)

and later you do:

$x = 'Hose';
echo $v;

and you want it to print
Up your Hose with a Hose
?

It might be possible with 'eval', if I have interpreted the
question correctly.
