Use = null.

You can not unset a single array element i think

[AN-net]

according to PHP.net you can>_> http://us2.php.net/unset

also could you explain further "Use = null" thing.

Yes, you definitely can unset a single array element.
A likely reason for your problem is a mistake in your code.
However, it is impossible to tell what the mistake is unless you post your whole code.

nvm found it, i had to make the array associative instead of keyed:)
