如何在数组索引中添加特定循环

Question

Hi guys this is my code:

$Months = array(
    'Jan',
    'Feb',
    'Mar',
    'Apr',
    'May',
    'Jun',
    'Jul',
    'Aug',
    'Sep',
    'Oct',
    'Nov',
    'Dec'
);


foreach($Months as $value){  
    echo "$value ";
    echo date('Y');
    echo "<br>";

    foreach(range(1,31) as $Days) {
        echo $Days;
         echo " ";
    }

    echo "<br>";
}

and this is the output:

Jan 2017

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 

Feb 2017

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 

and so on.

How can I edit the index to output the following months and it's days.

Answer 1

foreach($Months as $key=>$value){  
    echo "$value ";
    echo date('Y');
    echo "<br>";
    $year = 2017;
    echo implode(" ", range(1, cal_days_in_month(CAL_GREGORIAN, $key+1, $year)));

    echo "<br>";
}
