Get all days and date for a given month

Question

Would like to retrieve all days and date for a given month. Have this currently which shows all the days for the current month, but how do I parse in a specified month instead?<

Answer 1

$list=array();
$d = 13;
$year = 2019;

for($m=1; $m<=12; $m++)
{
    $time=mktime(12, 0, 0, $m, $d, $year);          
    if (date('m', $time)==$m)       
        $list[]=date('D-d-m-Y', $time);
    }

In this one you can put a spesific number and outpout all the days in the year that have the same number. example i wanted to outpout all the 13th days of the month. (if you want to find every Friday 13th that what you have to use)
