php explode and force array keys to start from 1 and not 0

I have a string that will be exploded to get an array, and as we know, the output array key will start from 0 as the key to the first element, 1 for the 2nd and so on.

Now how to force that array to start from 1 and not 0?

It’s very simple for a typed array as we can write it like this:

array('1'=>'value', 'another value', 'and another one');

BUT for an array that is created on the fly using explode, how to do it?

Thanks.

Answer

$exploded = explode('.', 'a.string.to.explode');
$exploded = array_combine(range(1, count($exploded)), $exploded);
var_dump($exploded);

Done!
