php unset array element while keeping numbers in order

Question

I apologize in advance for this question - I'm sure it's been answered before, (hell, I've done it before), I just can't find anything in the search and my brain is drawing a blank...

I have an array in PHP where print_r outputs:

Array
(
    [0] => VALUE
    [1] => VALUE
    [2] => VALUE
    [3] => VALUE
    [4] => VALUE
)

I use unset($_SESSION['item'][$lineID]); to unset a particular line from the array, and I'm left with:

Array
(
    [0] => VALUE
    [1] => VALUE
    [3] => VALUE
    [4] => VALUE
)

Element [2] has been removed, so the resulting array is no longer numerically in order

(e.g. - [0][1][3][4] instead of [0][1][2][3] ).

What PHP command do I run on the resulting array to "take out blanks" and reformat it so that it is numerically in order from 1 to n

To reset array keys after unset()

$array = array_values($array);

freaking `array_values`..... that's it. /monday. – Brian Powell Aug 10 '15 at 20:21
I recommend using `array_splice` instead of unset, which eliminates the use of `array_values` – Ids Klijnsma Aug 10 '15 at 20:24
