Be careful when using the difference between 'Now' and a future value. It's not clear whether the truncation happens when getting the DateTime objects' values, during the calculation, or immediately before returning the result. When getting the difference between two DateTime objects with fractions of seconds, DateTime::diff() works under PHP 7.1. If there is an index on the datecolumn it will be used. Keep in mind that diff will convert the two DateTime objects from local time to UTC. '';?> in the "datetime" attribute you should put a machine-readable value which represent time , the best value is a full time/date with ISO 8601 ( date('c') ) ,,, the attr will be hidden from users and it doesn't really matter what you put as a shown value to the user,, any date/time format is okay ! Here's what I got:
The return value more specifically represents the interval to apply to the However, under PHP 5.6, the fraction is truncated. Given two dates (date1 and date2) and the task is to compare the given dates. MySQL performs comparisons muchfaster than PHP.
I found that DateTime::diff isn't as accurate as I thought. hour. When I search and read code about time and date problems developers have, I noticed that a lot of people still use the old PHP functions like Now I see you asking: why using DateTime instead of a bunch of PHP date functions?The instantiation is easy: you can pass to the constructor a date correctly formatted, or nothing if you want to use the actual date and time.You can then format the date in order to display it, in two lines of code:Output: whatever the current date is, correctly formatted.You want to format an unreadable timestamp into a nice and shiny easy-to-read date?Obviously you can as well output a timestamp if you need to:What about adding or retrieving a day, a minute, an hour of a date? minute. It seems that while DateTime in general does preserve microseconds, DateTime::diff doesn't appear to account for it when comparing.
Warning, there's a bug on windows platforms: the result is always 6015 days (and not 42...) Method 1: If the given dates are in the same format then use a simple comparison operator to compare the dates. When getting the difference between two DateTime objects with fractions of seconds, DateTime::diff() works under PHP 7.1. I really hope it’s the case!I invite you to read the PHP documentation about the You need PHP 5.2. Returns the difference between two DateTime objects Similar to what was mentioned by ianlenmac at gmail dot com /*small script to check if the given date is between the limit "Enter a date within next %d days the difference is %d" You can as well precise the timezone you want as a second argument:

Should the interval be forced to be positive? date ('c'). Minute du moment. Comparing two dates in PHP is simple when both the dates are in the same format but the problem arises when both dates are in a different format. You only need to use the proper You can as well use the constructor if you work on the current date:For the same result you could as well instantiate a I never use this last solution personally, simply because I never need to.In order to compare those two dates we use the method The output indicate that there is 1 day and 22 hours difference between the two dates.If you only want the seconds, hours or day of interval you can write:If you need to compare two DateTime object, it’s as simple as writing:Keep in mind that you need PHP 5.2.2 or greater for the comparisons to work.
