Question

I have got the following array.

Array
        (
            [1] => a
            [2] => b
            [3] => c
            [4] => d
            [5] => e
            [6] => f
            [7] => g
            [8] => h
            [9] => i
            [11] => j
            [13] => k
            [14] => l
            [15] => m
            [16] => n
            [17] => o
            [18] => p
            [19] => q
            [20] => r
            [21] => s
            [22] => t
            [23] => u
            [24] => v
            [25] => w
        )

as you can see number 10 and 12 don’t exist.
Is there a function, so that my array has a range from 1 to 23? So that it would look like this?

Array
        (
            [1] => a
            [2] => b
            [3] => c
            [4] => d
            [5] => e
            [6] => f
            [7] => g
            [8] => h
            [9] => i
            [10] => j
            [11] => k
            [12] => l
            [13] => m
            [14] => n
            [15] => o
            [16] => p
            [17] => q
            [18] => r
            [19] => s
            [20] => t
            [21] => u
            [22] => v
            [23] => w
        )

I hope you understand my problem. Thanks for any help.

If you want a zero-indexed array:

$new = array_values($array);

If you want to start with an aribitrary number (in this case: 1);

$new = array_combine(range(1,count($array)),array_values($array));
