!--? php

$date 1 = "2006-08-09";
Echo Date (' y-m-d ', Strtotime ("$date 1 +5 Day")), or, accordingly, to increase the month, the year, or the day to months or years
?>
Output: 2006-08-14

+++++++++++++ today, Yesterday, tomorrow, last week, next week +++++++++++++++

!--? php
date_default_timezone_set (' PRC '); Date ("y-m-d", "Time ()"), "
" in the TimeZone
Echo today:
echo "Yesterday:", Date ("Y-m-d", Strtotime ("1 day"), "
";
echo "Tomorrow:", Date ("Y-m-d", Strtotime ("+1 Day"), "
";
Echo "One week later:", Date ("Y-m-d", Strtotime ("+1 Week"), "
";
echo "2 days, four hours, two seconds after the week:", Date ("Y-m-d g:h:s", Strtotime ("+1 Week 2 Day 4 hours 2 Seconds"), "
";
Echo "Next week Four:", Date ("Y-m-d", Strtotime ("next Thursday")), "
";
echo "Last Monday:". Date ("y-m-d", "Strtotime"). "
";
echo "One months ago:". Date ("Y-m-d", Strtotime ("Last month"). "
";
echo "After one months:". Date ("Y-m-d", Strtotime ("+1 Month")). "
";
Echo "Ten years later:". Date ("Y-m-d", Strtotime ("+10 Year")). "
";

?>


$date 1 = "2006-08-09";
echo Date (' y-m-d ', Strtotime ("$date 1 +5 Day"); Accordingly, increase the month, year, Change day to Month
?>
Output Result: 2006-08-14

+++++++++++++ today, yesterday, tomorrow, last week, next week +++++++++++++++

Date_default_timezone_set (' PRC '); Default time zone
echo "Today:", Date ("Y-m-d", Time ()), "
";
echo "Yesterday:", Date ("Y-m-d", Strtotime ("-1 Day")), "
";
echo "Tomorrow:", Date ("Y-m-d", Strtotime ("+1 Day"), "
";
echo "One week later:", Date ("Y-m-d", Strtotime ("+1 Week")), "
";
echo "2 days a week four hours two seconds later:", Date ("Y-m-d g:h:s", Strtotime ("+1 Week 2 Day 4 hours 2 Seconds")), "
";
echo "Next week Four:", Date ("Y-m-d", Strtotime ("next Thursday")), "
";
echo "Previous Monday:". Date ("Y-m-d", Strtotime ("Last Monday")). "
";
echo "One months ago:". Date ("Y-m-d", Strtotime ("Last month"). "
";
echo "One months later:". Date ("Y-m-d", Strtotime ("+1 Month")). "
";
echo "Ten years later:". Date ("Y-m-d", Strtotime ("+10 Year")). "
";

?>
Not this one. To add natural months, some months 28 days. Some 31 days

$s = ' 2013-07-31 ';
echo Date ("Y-m-d", Strtotime ("$s +1 month");

Oh, take it for granted

echo Date ("y-m-d\n", Strtotime ("$s +7 month");
Get 2014-03-03
Select Adddate (' 2013-07-31 ', INTERVAL 7 month)
Get 2014-02-28

Obviously, PHP's performance is unsatisfactory.

Mktime can actually meet the requirements.

$t = ' 2013-07-31 '; Echo date ("Y-m-d", Mktime (0,0,0,date ("M") + 12,date ("D"), Date ("Y")). '
'; Echo date ("Y-m-d", Mktime (0,0,0,date ("M") + 3,date ("D"), Date ("Y")). '
'; Echo date ("Y-m-d", Mktime (0,0,0,date ("M") + 1,date ("D"), Date ("Y")). '
';



Results:
2014-07-312013-10-312013-08-31

$t = ' 2013-07-31 '; Echo date ("Y-m-d", Mktime (0,0,0,date ("M") + 2,date ("D"), Date ("Y"));

To 2013-10-01
