How retrieve repeater's row ids from foreach() loop

Hello everyone,

Usually, Iretrieve the row ID from the loop using get_row_index() function as per documentation.

However, as I want to order rows by sub_fields (startdate), I have to use a foreach() and then use an array_multisort(). But in the foreach() I cannot access the function get_row_index() anymore, so is there another method to achieve the same results, namely results ordered by startdate and having access to the row ID.

Here is my code, thank you.

<?php
$retraites = get_field('retraites', 157);

foreach($retraites as $key => $retraite) :
    $column_id[$key] = $retraite['startdate'];
endforeach;

array_multisort($column_id, SORT_ASC, $retraites);

foreach($retraites as $retraite) : 
    $startdate = date('Ymd', strtotime($retraite['startdate']));
    $enddate = date('Ymd', strtotime($retraite['enddate']));
    if($startdate > date('Ymd')) :
        date_i18n('d M Y', strtotime($retraite['startdate']));
    endif;
endforeach;
?>
