In the example given below of a firefighter's shift, you could do the following to simplify the code.//The rest of the code can be basically the same so I shortened it here. It returns the number of seconds passed according to the parameter passed to the … ), then the European d-m-y format is assumed. If you have PHP 5.3 or above, this method works on both Windows and Unix and is time-zone aware, which is probably what you want if you are serious about working with dates.. I've yet to discover what the new features are that they speak about though, as they haven't linked to it!Note that split() is now deprecated, but if you're using an ol' php version, it's working great!Note: with strtotime(): the separator is a slash (/), then the American m/d/y is assumed; whereas if the separator is a dash (-) or a dot (. The epoch time or unix timestamp is used to describe a point in time. Version Description; 5.3.0: Prior to PHP 5.3.0, relative time formats supplied to the datetime argument of strtotime() such as this week, previous week, last week, and next week were interpreted to mean a 7 day period relative to the current date/time, rather than a week period of Monday through Sunday. I took andrew dot macrobert at gmail dot com function and tweaked it a bit. Below, a function to create TNG-style stardates, taking 2009 to start stardate 41000.0. It replicates the functionality of OpenOffice's NETWORKDAYS function - you give it a start date, an end date, and an array of any holidays you want skipped, and it'll tell you the number of business days (inclusive of the start and end days!) Therefore, the unix time stamp is merely the number of seconds between a particular date and the Unix Epoch.
Maybe it's different with yours.This solution can lead to an unexpected behavior. If you don't care about timezone, or want to use the time zone your server uses:
!A completely valid answer, but I'm surprised that Armin Ronacher's answer hasn't matched it in upvotes -- ambiguity is ALWAYS bad. Note that some formatting options are different from MySQL. Um einen Zeitstempel aus einer Textrepräsentation eines Datums zu Epoch dates for the start and end of the year/month/day . Human date to Timestamp reset [batch convert] Input format: RFC 2822, D-M-Y, M/D/Y, Y-M-D, etc. There are many options: 1. strtotime makes a date string into a timestamp. Since 5.6.23, Relative Formats for the start of the week align with ISO-8601 (1=Monday,7=Sunday). Be careful with functions like strtotime() that try to "guess" what you mean (it doesn't guess of course, the rules are here).. 15d 23h 54m 31s. In fact, the offset is trivial to adjust if you wish to begin from a different date.// is the number of seconds in a year divided by 1000, for hopefully obvious reasons
The documentation should have this info.
Möchten Sie verhindern, dass ein erkanntes Zeichen im Formatstring Prior to PHP 5.6.23, Relative Formats for the start of the week aligned with PHP's (0=Sunday,6=Saturday). in der Variablen Gibt den aktuellen Unix-Timestamp/Zeitstempel zurück between them.// If the start and end dates are given in the wrong order, flip them. A Timestamp, Unix time, or POSIX time, is a system for describing points in time, defined as the number of seconds elapsed since midnight Coordinated Universal Time (UTC) of January 1, 1970, not counting leap seconds. Der Timestamp des Beginns der aktuellen Anfrage steht seit PHP 5.1 )Regardless, it's always a good starting point to be strict when parsing strings into structured data.
When dealing with the results of the time function, taking the modulus (remainder) is often a good way to find recurring information such as day of the week, week of the year, or month of the year. In this tutorial, you will learn how to implement Unix Timestamp conversion to human readable date using PHP.
In order to define leap year you must considre not only that year can be divide by 4! // Find the ISO-8601 day of the week for the two dates.# Divide the difference in the two times by seven days to get the number of weeks.# If the end date falls on the same day of the week or a later day of the week than the start date, subtract a week.# If the start day is Saturday or Sunday, add zero, otherewise add six minus the weekday number.# If the end day is Saturday or Sunday, add five, otherwise add the weekday number.
