I think I know this one.

Saying array[foo] without quotes is something you can (usually) get away
with but it's deprecated. Bad habit. If you have error reporting set to
report 'notices', PHP will give you a warning about it.

Notice: PHPDocument1 line 5 - Use of undefined constant foo - assumed
'foo'

btw, if you want to embed $array["foo"] within a doble-quoted string, you
can do it protecting it with {}.

echo "Value of \$array["foo"] is now {$array["foo"]}, isn't that
fascinating.";
