Variable Variables

I'm using variable variables in a script, but there's one annoying thing that I can't seem to figure out.

$foo="egg";

then

${"x_$foo"} is the same thing as $x_egg

but...

${"$foo_x"} is not the same thing as $egg_x

I have to have a variable where the first part is another variable and the last part is _x.

Any help is appreciated.

I find with variable variables it's best to construct the variable name first as a string.

e.g.

$bit ="nice";
$egg = "people";
$thing = "$bit_$egg";

${$thing} = $nicepeople;

If that makes any sense i hope it helps.

You rock...it was the ${$thing} that made it work. :-)
