Change key name in 2-Dim Array

[Hayyel]

Hello,

I have recieved excellent help here before and after many hours of no results on my own thought I would come back and ask.

If I have:

PHP Code:

Array
(
    [1] => Array
        (
            [username] => Anonymous
        )

    [2] => Array
        (
            [username] => Test
        )

    [3] => Array
        (
            [username] => AdsBot [Google]
        )
) 


How do I change the [username] to [name]?

If you just want to change index name, try this:

PHP Code:

$new_array = array();
foreach ($original_array as $key => $value)
{
    $new_array[$key] = array('name' => $value['username']);
}

That worked great. Now that the two arrays are the same as far as format I thought I could run an array_diff on them but it returns as an empty array. I am assuming this is because they are two dimensional arrays.

I'll have to sort them somehow and then compare them... probably with some sort of nested foreach loop.

Am I on the right track?

Yes, also, take a look at examples using array_multisort().
