php - Removing exactly one month from a date -

-

it seems can't use strotime if need reliable , accurate date manipulation. example, if month has 31 days, appears strtotime minuses 30 days, not whole month.

so, example, if $event["enddate"] equal "2013-10-31 00:00:01", following code:

echo date("y/n/j", strtotime('-1 month', strtotime($event["enddate"]));

ouputs: 2013/10/1 instead of 2013/09/30.

question: how know how not it, there another, more accurate, way make php subtract (or add) whole month, , not 30 days?

the main issue 2013/09/31 not exist better approach use first day or last day of previous month. 

$date = new datetime("2013-10-31 00:00:01"); $date->modify("last day last month"); echo $date->format("y/n/j"); // 2013/9/30

when date 2013-10-15

$date = new datetime("2013-10-15 00:00:01"); $day = $date->format("d"); $year = $date->format("y");  $date->modify("last day last month"); $month = $date->format("m");  if (checkdate($month, $day, $year)) {     $date->setdate($year, $month, $day); }  echo $date->format("y/n/j"); // 2013-9-15
