How to Reindex PHP Arrays Starting from 1 Instead of 0?

Reindexing Arrays with Starting Index of 1 in PHP

When dealing with arrays, it can be necessary to reindex them for various reasons. This includes starting the index at a different value, such as 1 instead of the default 0. Here's how to accomplish this in PHP:

Starting at 0

To reindex an array starting at 0, use the array_values() function, which returns an array containing the values of the original array:

$iZero = array_values($arr);

Starting at 1

For a starting index of 1, utilize the array_combine() and range() functions:

$iOne = array_combine(range(1, count($arr)), array_values($arr));

This combines an array of consecutive integers starting at 1 with the values of the original array.
