I removed the double quotes, as they serve no purpose there.

For an indexed array, use:      unset 'a[i]'
For an associative array, use:  unset 'a[$i]'

In both cases, use single quotes, and all will be well.

(In the indexed array case, there is another pitfall involving code
injection in the arithmetic context, so only use sanitized index values.)
