try changing:
echo "$$temp\n";
to
echo $$temp."\n";
or even
echo ${$temp}."\n";
does that work?

Subject: [PHP] to evaluate ...
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
Sorry for bothering you, but I really didn't find answeres on dejanews and
in the tutorial, or better, I did not see them.
I need the following variables:
$width1
$width2
$width3
.
.
.
$widthn
Because it is not shure, how many they are, I need to construct them.
And because I need them in a <form> as "name" I could not use arrays (or
did I miss something here???).
So I tried the following, and it works:
(just to look that it works...)
[...]
$tmp = "bar$z_j";
while ($z_i <= $$tmp) {
echo "$$tmp\n";
$z_i++;
}
[...]
Ok, now the real problem starts:
if ($z_bars < $bars) {
$z_i = 1;
$rest = 100;
while ($z_i <= $z_bars) {
$temp = "width_bar$z_i";
echo "$$temp\n";
[...]
Guess what, yes!!, it is _not_ working.
So i start to experiment around and also tried to use eval()
but all I ever get was
width_bar1, width_bar2, width_bar3
or even worse
$width_bar1, $width_bar2 ....
and not something like I wanted it:
30, 50, 20
because
width_bar1 should be 30 for example and not to print out width_bar1 ....
I bash I would do it this way:
eval TEMP=\$width_bar$z_i
any ideas?
