私はあなたのコードをテストしました - それは私のために働きます:
function getMaxTillDate($timezone){
$threemonth = new \DateTime('now', new \DateTimeZone($timezone) );
var_dump(1, $threemonth);
$threemonth->setTime(23, 59, 59);
var_dump(2, $threemonth);
$threemonth->add(new \DateInterval('P0Y90DT0H0M'));
var_dump(3, $threemonth);
$maxday = $threemonth->format('t');
var_dump(4, $threemonth, $maxday);
$threemonth->setDate($threemonth->format('Y'), $threemonth->format('m'), $maxday);
var_dump(5, $threemonth);
$threemonth->setTimezone(new \DateTimeZone('UTC'));
var_dump(6, $threemonth);
return $threemonth;
}
$tz = "Europe/Berlin";
var_dump(getMaxTillDate($tz));
結果:
int(1)
class DateTime#1 (3) {
public $date =>
string(19) "2013-01-15 22:29:59"
public $timezone_type =>
int(3)

}
