Well, IMHO you shouldn't do in-string variables as you never know if
it will work. In this case, it won't YOu should do something like
this:

$query='delete from feedback where id='.$delete[$i];

Single quotes tell PHP not to look for variables in the string. A
period concatenates. There's actually a better solution, too:

$query='delete from feedback where
id="'.mysql_real_escape_string($delete[$i]).'"';
