Reset indexes to 1-based array

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));

Answer 2

$new_array = array_values($old_array);

Answer 3

Just add an element to the beginning, rekey and then shift it off.

$array = array_values(array_unshift($array, 'blank'));
unset($array[0]);

I didn't test it but that should do it.

Answer 4

One way to do it is:

$newArray = array();
foreach($oldArray as $val):
    $newArray[] = $val; //add the value to the new array
endforeach;
