How to delete an array element based on key?

Question

Possible Duplicate:
How to delete an element from an array in php?

For instance,

Array(      
    [0] => Array
        (
            [0] => hello
            [1] => open
        )

    [1] => Array
        (
            [0] => good
            [1] => center
        )

    [2] => Array
        (
            [0] => hello
            [1] => close
        )
)

I want to delete the element which key is 1, after the operation:

Array(
    [0] => Array
        (
            [0] => hello
            [1] => open
        )

    [2] => Array
        (
            [0] => hello
            [1] => close
        )
)

The answers for this question seem to answer "How do I delete elements from an array using an _index_ and not a _key_. — Lucas, Apr 05 '16 at 18:48
@LucasMorgan actually there's no difference, the index is the key for those without an explicit index. — Prajwol Onta, Feb 25 '20 at 12:06

You don't say what language you're using, but looking at that output, it looks like PHP output (from print_r()).
If so, just use unset():

unset($arr[1]);

this looks like PHP to me. I'll delete if it's some other language.

Simply unset($arr[1]);
