Changing key name in array

Question

I have an array called $eduAdd and I'm adding a string to the beginning of it like this:

array_unshift($eduAdd, $userId);

This is the result:

Array
(
    [0] => 3
    [fieldId] => Array
        (
            [0] => 4
        )

    [educationTitle] => Array
        (
            [0] => g
        )

    [educationDegree] => Array
        (
            [0] => g
        )

)

How can I rename [0] => 3 to ['userId'] => 3

Instead of using array_unshift just use $eduAdd['userId'] = $userId in the first place;

+ But note that `$eduAdd['userId']` would not add it has the first element ... – Baba Mar 29 '13 at 21:58
I need `['userId'] => 3 ` as the first element – Paul Dessert Mar 29 '13 at 21:58
Oh... I missed that point though it seems pointless to me – Musa Mar 29 '13 at 22:00
@Musa - You're right, it's pointless. I just looked at the code again and it does not matter. I thought it did at first, but it will work at the end. Been a LONG 2 days ;) Thanks – Paul Dessert Mar 29 '13 at 22:02

If it needs to be the first element (although pointless in an array), try using array_merge() -

$userId['userId'] = $userId
$eduAdd = array_merge($userId,$eduAdd);
