For some reason when removing items from an array I am left with keys like 0, 2, 3, 4, 6, 9 instead of 0, 1, 2, 3, 4, 5. So I am trying to figure out why, and what I can do to fix it without sorting everything via sort() as that will put stuff in order. I just want to re-key in a matter of speaking.

Use array_values() to get the values of the original array and return them to a new array. That new array with contain new numerical keys.

$new_array = array_values($old_array);

Since the keys don't necessarily matter, you can just run your final result array through array_values(). It leaves all the values in the order they already were, resetting all the keys to sequential numeric values.

You should use array_splice() to remove elements from your array so it changes the key the way you wish at the same time.
