I have no idea where to get help on RE stuff. Since it's for a PHP app
I thought I would ask here to see if there was some RE pros. Basically
I'm doing some template stuff and I wanted to use a
preg_replace_callback function to call another function when the
criteria of the RE expression is matched but have no idea how to
accomplish it.

So I start with this:
/<(input|select|textarea)[^>]*name\s*\=\s*\"[_a-zA-Z0-9\s]*\"[^>]*>/

but need to modify it so it only matches if it has '{' characters in
the name but to not match if it does not.

So this would not match:
<input name="test">

But this would match:
<input name="test{0}">

Thanks much in advance.
