This would be the logical way to do it (as I see it):
define('MY','pre_');
$a = dog;
$new_var = MY.$a;
$$new_var and $pre_dog are the same :)

It seems to me that the use of a temp variable may be the clearest

So the following two would be the same:
$$tmp = Spot;
$MYdog = Spot;
Good Luck,

Thanks Jason and Christoper for replying, here is the solution I came up
with. It takes into account that there could be multiple instances of what
I'm looking for on the same line - got it working late last night
I've a question regarding variable variable I was hoping someone could help me with:
All the examples in the manual have the entire variable name being variable e.g.
$a = hello and
$$a being the same as $hello
What I need to do, however, is append a variable portion to a constant prefix. So

have a set of variables that are named $MYdog, $MYcat etc. and I need to do
$a = dog
${MY$a} being the same as $MYdog
Can this be done, and if so - how? I can't get
