How to Re-Index Array Values in PHP

Re-indexing an array to assign numeric keys starting from 0 is a common requirement in PHP programming. 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, PHP offers the array_values() function. When applied to an array, it generates a new array that consists of the original array's values, with numeric keys starting from 0:

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

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

The array_values() function is particularly useful when you need to iterate over an array sequentially and rely on the index values. By using the re-indexed array, you can avoid having to deal with unpredictable or irregular key names.
