Reset the numeric keys of an array

I have an array like this

$array = array(
  1 => 'one',
  2 => 'two',
  3 => 'three',
  'row' => 'four',
  'newRow' => 'five',
);

I need to re-index the numeric keys - 1, 2, 3.

Expected Output:

$array = array(
  0 => 'one',
  1 => 'two',
  2 => 'three',
  'row' => 'four',
  'newRow' => 'five',
);

I've tried with array_values, but the string keys also gets indexed.

What is the best way to do this?

Thanks.

Use array_merge to reindex you array.

The code:

<?php
$array = array(
    1 => 'one',
    2 => 'two',
    3 => 'three',
    'row' => 'four',
    'newRow' => 'five',
);
$reindexed_array = array_merge($array);
var_dump($reindexed_array);

The result:

array(5) {
    [0]=> string(3) "one"
    [1]=> string(3) "two"
    [2]=> string(5) "three"
    ["row"]=> string(4) "four"
    ["newRow"]=> string(4) "five"
}

A working example you can find here: https://3v4l.org/Om72e. More information about array_merge: http://php.net/manual/en/function.array-merge.php

        $array = array(
          1 => 'one',
          2 => 'two',
          3 => 'three',
          'row' => 'four',
          'newRow' => 'five',
        );

        $newArray = [];

        foreach ($array as $key => $value) {
            if (!is_numeric($key)) {
                $newArray[$key] = $value;
            } else {
                $newArray[] = $value;
            }
        }

        var_dump($newArray);
        die();
