How do I add a certain number of days to the current date in PHP? I already got the current date with: $today = date('y:m:d'); Just need to add x number of days to it php supports c style date functions. You can add or substract date-periods with English-language style phrases via the strtotime function. examples... $Today=date('y:m:d'); // add 3 days to date $NewDate=Date('y:m:d', strtotime("+3 days")); // subtract 3 days from date $NewDate=Date('y:m:d', strtotime("-3 days")); // PHP returns last sunday's date $NewDate=Date('y:m:d', strtotime("Last Sunday")); // One week from last sunday

由 陌路散爱 提交于 2019-11-27 16:31:37
问题 I am using Joda time api in a Spring 3.0 project for the very first time. Now I have a start and end date and I want to get the date for all mondays between these two dates. How can I do this ? I have no idea where to start, can someone please advise. I looked at theis post Joda Time: How to get dates of weekdays on some date interval? and it offered some sort of guidance but its still somewhat vague due to little experience with joda. 回答1: LocalDate startDate = new LocalDate(2011, 11, 8);

Get number of weekdays in a given month

I want to calculate the number of weekdays days in a give month and year. Weekdays means monday to friday. How do i do it ? Some basic code: $month = 12; $weekdays = array(); $d = 1; do { $mk = mktime(0, 0, 0, $month, $d, date("Y")); @$weekdays[date("w", $mk)]++; $d++; } while (date("m", $mk) == $month); print_r($weekdays); Remove the @ if your PHP error warning doesn't show notices. You don't need to count every day in the month. You already know the first 28 days contain 20 weekdays no matter what. All you have to do is determine the last few days. Change the start value to 29. Then add 20

Algorithm to add or subtract days from a date?

I'm trying to write a Date class in an attempt to learn C++. I'm trying to find an algorithm to add or subtract days to a date, where Day starts from 1 and Month starts from 1. It's proving to be very complex, and google doesn't turn up much, Does anyone know of an algorithm which does this? The easiest way is to actually write two functions, one which converts the day to a number of days from a given start date, then another which converts back to a date. Once the date is expressed as a number of days, it's trivial to add or subtract to it. You can find the algorithms here: http://alcor

How can I calculate the number of days between two dates in Perl?

由 耗尽温柔 提交于 2019-11-27 04:34:13
问题 Heylo, I want to calculate (using the default Perl installation only) the number of days between two dates. The format of both the dates are like so 04-MAY-09. (DD-MMM-YY) I couldn't find any tutorials that discussed that date format. Should I be building a custom date checker for this format? Further reading of the Date::Calc on CPAN it looks unlikely that this format is supported. Thanks. 回答1: If you care about accuracy, keep in mind that not all days have 86400 seconds. Any solution based

问题 This question already has answers here : Closed 7 years ago . Possible Duplicate: How can I create a Zerofilled value using JavaScript? I have to output a day number that must always have 3 digits. Instead of 3 it must write 003 , instead of 12 it must write 012 . If it is greater than 100 output it without formatting. I wonder if there's a regex that I could use or some quick in-line script, or I must create a function that should do that and return the result. Thanks! 回答1: How about:
