Converting a variable to a String

[Anon]

Hello people.

Does anybody know how to convert a variable to a string (as in the variable itself, not it's value)?

I have several <image type="submit"> buttons on a page, all resuling from a while loop.
they look like this:

echo '<input name=button'.$xid.'>';

The value which I can retrieve on submission looks like this:

$button79_x

I need to retrieve the number (in this case 79) from the variable. It is the variable $xid.

The way I see it I need to convert the variable name itself to a string and then fetch the number out. I have, however, no idea how to do this.

Any ideas?

thanks,
feisty.

I have done it using the eval function

I'll put the exact code up when I get home, as I don't have it with me.

echo ${"button" . $xid . "_x"};
