simple way to change the key value of an array element

Question

I am reading in a bunch of multi-dimensional arrays, and while digging through them I have noticed that some of the keys are incorrect.

For each incorrect key, I simply want to change it to zero:

from:

$array['bad_value']

to:

$array[0]

I want to retain the value of the array element, I just want to change what that individual key is. Suggestions appreciated.

Cheers

Answer 1

Bruteforce method:

$array[0] = $array['bad_value'];
unset($array['bad_value']);

Answer 2

if you change multiple keys to 0 you will overwrite the values...

you could do it this way

$badKey = 'bad_value';
$array[0] = $array[$badKey];
unset($array[$badKey]);

Answer 3

$array['0'][] = $array['bad_value'];
unset( $array['bad_value'] );

Then it will be an array in $array['0'] with values of broken elements.

Answer 4

Well seeing as you said the keys can be changed to any numeric value how about this?

$bad_keys = array('bad_key_1', 'bad_key_2' ...);
$i = 0;
foreach($bad_keys as $bad_key) {
    $array[$i] = $array[$bad_key];
    unset($array[$bad_key]);
    $i++;
}

EDIT: The solution I gave was horrible and didn't really solve the problem as there are multiple bad keys, this should be better.
