Ok,...
what sort situations would you benifit using the first method?
ie
is it more suiteable to making some conditions
eg
$a = foo;
while {$$a <= bar)
echo "$a";
endwhile;

well, the first method is the same as saying
$a = "foo";
$foo = "bar";
echo "$a $foo";
whereas the second method is appending "bar" to $a (thus making it "foobar")
In first method, you get two variables, the second, just one

howdy,
I'm just curious here about varible varibles ... I know that you can, well
it's documented that you can, do the following
<?
$a = foo;
$$a = bar;
echo "$a $$a";
?>
which will produce foo bar
now what I am curious about is, how much of a difference does that really
make when you compare it to..
<?
$a = foo;
$a .= bar;
echo "$a";
?>
Cheers
Peter
