Change key name in 2-Dim Array

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:

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:


$new_array = array();
foreach ($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() (http://www.php.net/manual/en/function.array-multisort.php).
