PHP - Remove , merge Item Array

your solution is array_merge(), which will reindex a numeric array.

So if you have

$array[0] = "something";
$array[1] = "something else";
$array[2] = "yet another";

unset($array[1]);
$array = array_merge($array);

the result is

$array[0] = "something";
$array[1] = "yet another";
