well, arrays are always causing a mess in strings - especially as they
grow more complex - $foo[$bar[$i]['name']]['id'] might seem (somewhat)
logical to me, but the parser has a hard time - not to mention the added
headache of the string. The answer lies in { } - try

$foo['bar'] = "hello";
echo "well, {$foo['bar']} world";

- the $foo[bar] construction works, which is odd, since bar should
represent some undefined constant - it seems to me PHP falls back on
variables in the symbol table, if there's no constant?
