[RESOLVED] variable iteration

I'm stuck, with a very simple question. but i must be using the wrong search terms or something because I'm not finding my answer.

I have a series of variables
$var1
$var2
$var3
$var4
...
$var22

how can I use these variables in a loop?
eg:

for($i=1;$i<22,$i++){
$var$i = {whatever}
}

I know there's a way to do this but I cant' seem to find it.

Thanks for pointing me in the right direction.

okay. found it. double dollar signs.

$desired='var'.$i;
$$desired= {what I want}

you should consider using an array instead.

As dagon suggests, using an array is often far easier than what you're trying to do.

However, note that you could shorten this:

$desired='var'.$i;
$$desired= "your value here";

to this:

${"var$i"} = "your value here";

thanks, dagon and bradgrafelman.
