doing variable in variable? is that possible?

[Anon]

Hey all..
I've got a problem..

Each editbox in a form has his own name..
I've made this name with a counter called
$valuecount which is increased everytime with 1.
So I'm giving them the name val$valuecount,
which will give them names like val1,val2,val3 and so on..

Now when I press submit I want them to write to a textfile...
($key is another string... so I need it to place the $key variable, a = sign,
and then the $val$valcount in the textfile)

So I use this line...
fwrite($fp,"$key=$val$valuecount \r");

But that doesn't work... somehow it can't use a variable in a variable..

Someone knows why and how to solve it?

Thanks!

Are you trying to do an array?

You MUST begin variables with a $ or a &$, I cannot stress this enough.

$key=$val.$valuecount should work ...

yes, it is, but you've got to do it in a specific way.

$foo="val".$valuecount;

$key=$$foo;
