Answer 1

You can't use table notation directly into string.
You can use concatenation like this :

echo '<option value="'.$row['rate'].'">'.$row['name'].'</option>'; 

Or wrap your table variables between {}

echo "<option value='{$row['rate']}'>{$row['name']}</option>"; 

Don't forget the quotes for the html value parameter, and the quotes for the index of the table.

Note : If you don't use quotes for the table index, it will try to match a constant and will fallback assuming it is a string if no constant has been found.
