根据给定的月份和年份，获得前三个月的年份

Question

Is there any way to get the previous three months if I am giving the year and month as input (in PHP). Suppose I am giving the values,

$month = "2";
$year = 2016;

It should return like below array,

Array ( [0] => '11 2015' [1] => '12 2015' [2] => '01 2016')

Answer 1

Use mktime

$month = "2";
$year = 2016;

for($i=3;$i>0;$i--){
    $arr[]=date("m-Y", mktime(0, 0, 0, $month-$i, 01, $year));


}
print_r($arr);

output

Array ( [0] => 11-2015 [1] => 12-2015 [2] => 01-2016 )

EDIT for your comment replace m with n

$arr[]=date("n-Y", mktime(0, 0, 0, $month-$i, 01, $year));
