This really is a faq: if you want to substitute anything other than a simple variable
name into a double-quoted string, you MUST use curly braces {} to delimit it. So:
echo "<option value=game1>${teams[$r.'1']}</option>";
is what you need.
(Note: I also treat variable names including underlines _ as being not simple, as I've
had cases where PHP seems to parse these incorrectly -- for example,
"...$long_name..." is treated as "...${long}_name...", not "...${long_name}...".)
If you have any doubts, include the {} -- even for simple variables, it does no harm
to write, for example "...${var}...".
I do sometimes wonder whether the {} should be made mandatory in some future version,
even for simple variables, to avoid exactly this kind of confusion.
Cheers!
Mike
