Question

I have array with data and key [1, 2, 4, 5].

$array = xxxx;

this is:

                       [array] => Array
                            (
                                [1] => Array
                                    (
                                        [test] => fdasdfs24
                                    )

                                [2] => Array
                                    (
                                        [test] => fdasdf23
                                    )

                                [4] => Array
                                    (
                                        [test] => fdasdf4
                                    )

                                [5] => Array
                                    (
                                        [test] => fdasdf34
                                    )

                            )

How can i reset indexes in this and array? I would like receive: [1, 2, 3, 4]

                       [array] => Array
                            (
                                [1] => Array
                                    (
                                        [test] => fdasdfs24
                                    )

                                [2] => Array
                                    (
                                        [test] => fdasdf23
                                    )

                                [3] => Array
                                    (
                                        [test] => fdasdf4
                                    )

                                [4] => Array
                                    (
                                        [test] => fdasdf34
                                    )

                            )

how can i make it? Maybe is for this some function? I dont want doing this mannually – this is only example.

Answer 1

As you index starts as 1 instead of 0, you need to use range function and with the help of array_combine you get the resultant array.

array_combine(range(1,4),  array_values($array));

To make it more general you can use this,

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