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 "${teams[$r.'1']}";
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

or a variation on this theme

Re: [PHP] HTML lists & PHP
maybe you can try something like this... $r1 = "game1" $r2 = "game16"; echo ""; echo "$teams[$r1]"; echo "$teams[$r2]"; echo ""; Greets, Edward > I keep getting parse error with this code: > ($teams[] is a big array that I got by using mysql_fetch_array) > > >$r = "game"; >echo ""; >echo "$teams[$r.'1']"; >echo "$teams[$r.'16']"; >echo ""; > > Im trying to make a dropdown list. > > Here is the error message: > Parse error: parse error, expecting `']'' in > /home/filanya/www/madness/bracket.php on line 65 > > (line 65 is the third line down) > > THANKS > -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]
