How to Reindex a PHP Array with Consecutive Numeric Keys?

Reindexing PHP Arrays

To resolve the issue of missing array indexes, you can use the array_values function in PHP. This function reindexes an array by creating a new one with consecutive numeric keys starting from 0.

Example:

<code class="php">$myarray = [
    0 => 'a->1',
    1 => 'a-7',
    '3' => 'a-8',
    4 => 'a-3',
];

$reindexedArray = array_values($myarray);

print_r($reindexedArray);
// Output:
// Array
// (
//     [0] => a-1
//     [1] => a-7
//     [2] => a-8
//     [3] => a-3
// )</code>
Copy after login

By calling array_values($myarray), we create a new array $reindexedArray that has consecutive indexes from 0 to the last element. This effectively reindexes the original array and removes any missing indexes.
