Answer 1

试试这个希望它有帮助

$newdate = strtotime(date("Y-m-d", strtotime($date)) . " +12 week");

Answer 2

$month = 2;
$year = 2012;


$date = date('Y/M/d',strtotime('First Saturday '.date('F o', @mktime(0,0,0, $month, 1, $year))));
echo $date;
echo "<br/>";
$newdate = strtotime ( strtotime ( $date ) . '+12 week' ) ;
$newdate = date ( 'Y/M/d' , $newdate );

echo $newdate;
