How to Reindex an Array in PHP with `array_values()`?

Reindexing an Array in PHP

In PHP, you may encounter situations where you have an array with unset indices, resulting in gaps in the index sequence. To address this, you need to reindex the array to ensure a continuous index order.

How to Reindex an Array Using array_values

The array_values() function provides a straightforward solution for reindexing an array. It extracts the values from the original array and assigns them to new keys with sequential indices starting from 0.

To reindex your array, simply use the following code:

<code class="php">$myarray = array_values($myarray);</code>

After executing this code, your $myarray will be reindexed as follows:

[0] => a->1
[1] => a-7 b->3
[2] => a-8 b->6
[3] => a-3 b->2

The gaps in the previous index sequence have now been removed, and the array's indices range from 0 to 3.
