PHP gets today, yesterday, tomorrow's date

directly on the code, in explanation

 
  ";       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 after:". 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")). "
";   ? >

The function of the Strtotime () function is to parse the datetime description into a Unix timestamp int strtotime (string time [, int now]) PHP Week gets the code: date ("L");// Data can be obtained in English for weeks such as Sundaydate ("w");//This can get the number of weeks such as 123, note 0 is Sunday get Chinese week can be so $weekarray=array ("Day", "one", "two", "three", "four", "five", "six echo "Week". $weekarray [Date ("W")]; Gets the specified date: $weekarray =array ("Day", "one", "two", "three", "four", "five", "six"); Echo "Week". $weekarray [ Date ("W", "2011-11-11")]; because the date function is so powerful, he can do all this work. I enclose a table in the handbook. A-"AM" or "PM" A-"AM" or "PM" D-a few days, two digits, if less than two bits are preceded by 0; such as: "01" to "D"-Day of the week, three letters of English; such as: "Fri" F-month, English full name; such as: "January" h-12 hours of the hour system; such as: "01" to "a" H-24 hours of the hour system; such as: "00" to "g-12" hours of the hour system, less than two does not fill 0; such as: "1" to three "G-24 hours of the hour, less than two does not fill 0; such as: "0" to "the" I-minute; such as: "00" to "the" J-a few days, two digits, if less than two bits do not fill 0; such as: "1" to "~" L-day of the week, English full name; such as: "Friday" M-month, two digits, if less than two digits in front of 0; such as: "01" to "three" N-month, two digits, if less than two will not fill 0; such as: "1" to "ten" M-month, three English letters; such as: "Jan" s-second; such as: "00" to "the" S-the end of the English ordinal, two English letters; such as: "th", "nd" T-Specify the number of days of the month; e.g. "28" to "U"-Total number of seconds W-number of days of the week, such as: "0" (Sunday) to "6" (Saturday) Y-year, four digits; such as: "1999" Y-year, two digits; such as: "" "Z-the first day of the year; such as: "0" to "365"
