Question

how to get the previous 3 months in php ex(If i say DEC.. It should display the previous 3 months i.e., OCT NOV DEC)

Answer 1

You can use the strtotime function like this:

echo date('M', strtotime('-3 month'));

So you specify previous dates with minus sign.

echo date('M', strtotime('0 month'));
echo date('M', strtotime('-1 month'));
echo date('M', strtotime('-2 month'));
echo date('M', strtotime('-3 month'));

Results:

Dec
Nov
Oct
Sep

You can do the same if you are using a loop like this:

for ($i = -3; $i <= 0; $i++){
  echo date('M', strtotime("$i month"));
}

Results:

Sep
Oct
Nov
Dec
