How to Re-index Array Values in PHP Starting from Zero?

Re-indexing Array Values in PHP

When working with arrays in PHP, there might be situations where you need to re-index the values to start at a specific index, such as zero.

Consider the following situation:

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

The array keys are strings representing the names of the values. However, if you want to rename these keys to start from zero, you can use the array_values() function.

Solution: array_values()

The array_values() function returns a new array with values re-indexed starting from zero. It preserves the values of the original array, but changes the keys to sequential integers.

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

The resulting array, $reindexedArray, will now have the following structure:

<code class="php">[0] => 3
[1] => 1
[2] => 1
[3] => '2009-09-24 09:02:05'
// ... additional re-indexed array elements</code>

Using array_values(), you can easily re-index the values of an array in PHP, starting from a specific index if necessary.
