RE: [PHP] to evaluate ...

[Martin Towell]

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

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?

[hugh danaher]

If your heart is set upon using $width1... then write your variable like in
the following:

for ($i=1;$i=$some_end_number;$i++)
{
${width.$i}=something width;
}

 Yes, you're missing something :) You can use arrays in forms, just use
names
 like width[0], width[1] etc.
