How to Reindex a PHP Array Starting from 1?

Reindex an Array and Shift Indexes to Start from 1 in PHP

You have an array with keys starting from 2, and you want to reindex it with keys starting from 1.

To achieve this, you can use a combination of array functions in PHP:

1. Use array_values() to Extract Object Values:

$values = array_values($originalArray);

2. Use array_combine() and range() to Reindex with Indexes Starting from 1:

$reindexedArray = array_combine(
    range(1, count($values)),
    $values
);

Output:

array (

[1] => Object
    (
        [title] => Section
        [linked] => 1
    )

[2] => Object
    (
        [title] => Sub-Section
        [linked] => 1
    )

[3] => Object
    (
        [title] => Sub-Sub-Section
        [linked] => 
    )

)
