![]() $timestamp = time() - (60*60) // set a unix timestamp here. $filename = "test-php-file.txt" // specify name for file to create/edit timestmap of The following snippet will programmatically set a file to have been edited at a specific unix timestamp. If you want to create the timstamp string and insert it rather than rely on MySQL creating the timestamp for you, then you can use this: echo date('Y-m-d H:i:s', time()) This is also the same as: echo strtotime('09:36:00') - strtotime('TODAY') If you want to know how many seconds a time like 36 minutes past 9 AM is in seconds since midnight execute the following: echo strtotime('09:36') - strtotime('TODAY') This can easily be done because it is already in the format that the DateTime object expects $localDate = \Brick\DateTime\LocalDate::fromNativeDateTime(new DateTime($dbRow)) The following is a quick way to convert from a MySQL or PgSQL date string to a LocalDate object. Working With Brick\DateTime Create LocalDate From MySQL / PgSQL Date String ![]() The MySQL date format is actually already in Y-m-d format, so one can just use it directly in the constructor like so: $dateTime = new DateTime($mysqlDate) Ĭonvert DateTime To MySQL Format $mysqlDate = $dateTime->format('Y-m-d') Long answer: If you want an equilvalent function of time() in milliseconds first you have to consider that as time() returns the number of seconds elapsed since the 'epoch time' (), the number of milliseconds since the 'epoch time' is a big number and doesn't fit into a 32 bits integer. $datetime = DateTime::createFromFormat('m/d/Y', $americanStyleDate) If you need to create a DateTime object, then here are some useful snippets: Create From Specified Date Format $americanStyleDate = "" If you are using a date input field and pre-populating the value, you need to use code like this: ') outputs Friday 1st January 1999īe careful not to do this: $timestamp = strtotime("2nd January 1999") Timestamps are the number of seconds since 1 January 1970 00:00 UTC for some definitions of a timestamp, or the number of seconds since 1 January 1970 in the local time zone for some definitions of a timestamp. Use the date() function to output in a human readable form. Note that date() will always generate 000000 since it takes an integer parameter, whereas DateTime::format() does support microseconds if DateTime was created with microseconds. Since the timestamp is just an integer, you can print it or perform maths with it. # This is the the 1st of Feb, not the 2nd of Jan # This is the the 2nd of Jan, not the 1st of Feb PHP considers date strings with - to be English, and dates with / to be American. You now have the unix timestamp (number of seconds as an integer, since 1st January 1970) $timestamp = strtotime("1st January 1999") Converting User Input $timestamp = strtotime("") Parameters object Procedural style only: A DateTime object returned by datecreate () format The format of the outputted date string. If you need to do some complicated stuff, then I would recommend using these packages. Procedural style dateformat ( DateTimeInterface object, string format ): string Returns date formatted according to given format. Which itself makes use of the brick/date-time package. I have a package to help with time/date manipulation
