Answer 1

Based on your previous question and its accepted answer, you’re going to loop through the array anyway. While you’re doing that you can calculate the maximum value:

$maxUid = 0;

foreach ($yourArray as $key => $val) {
    $maxUid = max( $maxUid, $val[ 'uid' ] );
    // do everything else
}
