使用php获取下一个第15天和/或第30天的日期？(Get the date of the next 15th and/or 30th day with php?)

 我要求获取当前日期即将到来的下个月的15日和30日的日期。 （如果二月在范围内，当然必须是28/29）。 
 
 我可以使用mktime / strtotime或者使用其他方法吗？ 
 
 我得到了这个，但当然这只是为了这个和下个月的最后一天。 我需要即将到来的15日和30日。 
 
$cuota1 = date('t-m-Y', strtotime('+15 days'));
    return $cuota1;

$cuota2 = date('t-m-Y', strtotime('+30 days'));
    return $cuota2;

$cuota3 = date('t-m-Y', strtotime('+45 days'));
    return $cuota3;
 
 提前致谢。 

I require to get the dates of the upcoming 15th and 30ths of the next months as for the current date. (If February is within range it must be 28/29th of course).
 
Can I do this using mktime/strtotime or maybe using another method?
 
I got this but of course this is for only get the last day of this and next month. I need the upcoming 15ths and 30ths instead.
 
$cuota1 = date('t-m-Y', strtotime('+15 days'));
    return $cuota1;

$cuota2 = date('t-m-Y', strtotime('+30 days'));
    return $cuota2;

$cuota3 = date('t-m-Y', strtotime('+45 days'));
    return $cuota3;
 
Thanks in advance.
