I added the max function and it returned the highest number "17" for each developer and respective days.

$months = array();
foreach($best_day as $day) {
    $timestamp = strtotime($day['date']);
    $month = date('F', strtotime($day['date']));
    $date = date('jS', $timestamp);

    $dev = $day['user'];
    $comp = $day['compeleted'];
    $max = '';  
    $make_array[] = $day['compeleted'];
    $max = max($make_array); 

    if (empty($months[$month])) {
        $months[$month] = array();
    }

    $months[$month][$dev][] = [$max];
}

I only want to return the maximum number for each user in a month. For example, Alexandria will only show "3rd","7".

CodePudding user response：

Instead of pushing each date and amount onto a nested array, check if the current amount is greater than the amount there, and replace it if so.

$months = array();
foreach($best_day as $day) {
    $timestamp = strtotime($day['date']);
    $month = date('F', strtotime($day['date']));
    $date = date('jS', $timestamp);

    $dev = $day['user'];
    $comp = $day['compeleted'];
    if (!isset($months[$month][$dev]) || $completed > $months[$dev][$month][$dev][1]) {
        $months[$month][$dev] = [$date, $comp];
    }
}
