PHP - Change beginning of an Array

Question

I'd like to change the beginning of my array in PHP. Currently I've got:

Array
(
  [0] => Bla##
  [1] => Bla##
  [2] => Bla##
  [3] => Bla##
  [4] => Bla##
  [5] => Bla##

but I want

Array
(
  [6] => Bla##
  [7] => Bla##
  [8] => Bla##
  [9] => Bla##
  [10] => Bla##
  [11] => Bla##

I used array_splice($array, 14, 0, 'Bla##'); to insert a value at a specific index of my array, but if I use this my array starts from 0 and not from 6.

Thanks in advance!

Do you mean you want to change the indexes and leave the values the same? — RiggsFolly

$shift = 6;
$array = array_combine(range($shift, count($array)+$shift-1), $array);

Just shift all the array positions forward by 6 0->6, 1->7 etc

    $array = [Bla##,Bla##,Bla##,Bla##,Bla##,Bla##];
    $newarray = array();    // Shifted array
    for ($i=0; $i < count($array);$i++) {  
          $newarray[$i+6] = $array[$i];  
    }

You can use array_walk():

$n = 6;
array_walk($arr, function($value) use (&$x, &$n) {$x[$n] = $value; $n++;});
