Can I reset array keys?

[thox]

Best explained as an example:

$array[8] = 'Bob';
$array[17] = 'Geoff';
$array[2] = 'Alice';

Can I get the above array to become this?

$array[0] = 'Alice';
$array[1] = 'Bob';
$array[2] = 'Geoff';

The names are examples... I do not want any change in the order of the array. I simply want the keys to be like this so I can access the data more easily.

If there is not a simple solution that i have overlooked then I will post here later with more information of what I am actually trying to achieve.

Thanks in advance :)

there must be a simpler way but I am yakked if I can think of it right now ?


<?
$array[8] = 'Bob';
$array[17] = 'Geoff';
$array[2] = 'Alice';

//if you want
//sort($array);

$new=array_merge(array(),$array);
print_r($new);
?>

strangely the results of what you wrote do this:

Array
(
[0] => Bob
[1] => Geoff
[2] => Alice
)

which is actually in the wrong order.

$array[8] = 'Bob';
$array[17] = 'Geoff';
$array[2] = 'Alice';

^^^ with that as the original array, should it not come out as this?:

Array
(
[0] => Alice
[1] => Bob
[2] => Geoff
)

the code may still work for me as the array *should* have already been loaded in the correct order. thanks again for your help :)

I know that post is too old but since it is in google's result for the keyword 'php reset array keys' I have decided to add the solution to help others ;)

The first idea which came to my mind was this:
$threads = array('10'=>'one', '2'=>'two', '15'=>'three');
$keys = range(0, count($threads)-1);
$values = array_values($threads);
$threads = array_combine($keys, $values);

but later I have discovered that there is even more simple way :)
$threads = array('10'=>'one', '2'=>'two', '15'=>'three');
$threads = array_values($threads);

Good luck with your script

Thanks PHP6, I was looking for that. :thumbsup:

array_merge (http://php.ca/manual/en/function.array-merge.php)
Given a single array, it will reindex the values for you as long as they are integer based.

If your array is out of order, like the OP was talking about, run ksort() (http://php.net/ksort) on it before using array_values() (http://php.net/array_values) or array_merge() (http://php.net/array_merge).
