How to Reindex a PHP Array Starting from 1 Instead of 0?

Reindexing an Array with Indices Starting from 1 in PHP

To reindex an array with indices starting from 1 rather than 0, you can utilize two primary methods:

Method 1: Starting from Zero

If you desire an array's indices to start from zero, the following code snippet can be used:

$iZero = array_values($arr);

Method 2: Starting from One

Alternatively, if you prefer indices to begin from 1, you can implement the following code:

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

Understanding the Functions Involved

• array_values(): Retrieves the values of an array as a new array, ignoring the keys.
• array_combine(): Creates a new array by using one array for keys and another for values.
• range(): Creates an array of integers within the specified range.

By leveraging these functions, you can efficiently reindex your arrays to align with your desired index starting point.
