您可以通过捕获它来轻松处理异常,这将修复错误,因为您不再需要打扰该错误：

try {
    $newday = $a['dayz'];
    $endmonth = $a['monthz'];
    $newyear = $a['yearz'];
    $date = new DateTime("$newyear-$endmonth-$newday");
    $date->modify('+8 day');
    $year = $date->format('Y');
    $month = $date->format('m');
    $day = $date->format('d');
} catch(Exception $e) {
    # do nothing
}

至少在某些时候你需要进行错误处理.例外要求您这样做,DateTime抛出异常.
