[RESOLVED] insert to a specific place in array

[owaring]

i have an array called from db that is used for a menu bar.
the order of the menu bar is set in the sql statment,
i want to insert another item into this array between 2 oter items.

is that possible or do i need to order the array, (if so how???!!)

Let's say $menuArray is your array of menu items and $newPos is the position you want the new item to have and $newItem is that item. Here goes...

<?php

$front = array_slice($menuArray, 0, $newPos);
$middle = array($newItem);
$back = array_slice($menuArray, $newPos);

$newMenuArray = array_merge($front, $middle, $back);

?>

Hope this helps...

alimadzi's code can be simplified (and probably optimised) with the use of array_splice(), e.g.,

$newMenuArray = $menuArray;
array_splice($newMenuArray, $newPos, 0, $newItem);

Of course, if you do not actually need $newMenuArray, then you would just pass $menuArray as the first argument to array_splice().

thanks for that, the code i've written to build my menu relys on the array key name.
it seems by these methods i insert the new item with a numerical key.

can i rename a key??

found this user comment via the manual;

function array_insert (&$array, $position, $insert_array)
    {
    $first_array = array_splice ($array, 0, $position);
    $array = array_merge ($first_array, $insert_array, $array);
    }

array_insert ($data, 1, array ('archive' => $archive));
