How to Re-index an Array in PHP?

Re-indexing an Array in PHP

You may encounter a scenario where you need to re-index the values of an array. This can be useful for situations where you want to access array elements using consecutive numerical indices.

To re-index an array, you can use the array_values() function. This function returns a new array containing the values of the original array in numerical order.

For example, consider the following array:

<code class="php">$array = [
    'id' => 3,
    'user_id' => 1,
    'clan_id' => 1,
    'date' => '2009-09-24 09:02:05',
    ...
];</code>

To re-index this array, simply call the array_values() function:

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

The $reindexedArray variable will now contain the values of the original array in numerical order:

<code class="php">Array (
    [0] => 3
    [1] => 1
    [2] => 1
    [3] => 2009-09-24 09:02:05
    ...
) </code>

You can now access the array elements using consecutive numerical indices, making it easier to iterate over the array or perform other operations.
