The date() optionally accepts a time stamp if omitted then current date and time will be used. There are 2 common ways to create a range of dates in PHP: Using DateTime, DateInterval, and DatePeriod objects. You can exercise an enormous amount of control over the format that date() returns with a string argument that you must pass to it.
The date() function returns a formatted string representing a date. You can format this date and time in whatever format you wan. Now you have complete control over date and time. These are the top rated real world PHP examples of utime extracted from open source projects. The Unix timestamp contains the number of seconds between the Unix Epoch (Janu00:00:00 GMT) and the time. The PHP mktime () function returns the Unix timestamp for a date. If omitted, the current date and time will be used (as in the examples above). If you omit the time stamp, it works with the current time stamp as returned by time().įollowing table lists the elements contained in the array returned by getdate(). The optional timestamp parameter in the date () function specifies a timestamp. The function getdate() optionally accepts a time stamp and returns an associative array containing information about the date. But PHP offers excellent tools to convert a time stamp into a form that humans are comfortable with. Otherwise known as the Unix Timestamp, this measurement is a widely used standard that PHP has chosen to utilize. Timestamp: A timestamp is a number of seconds from January 1, 1970, at 00:00. This gives PHP a date range of between 14th December 1901 and 19th January 2038. This value can be positive or negative: so a value of -3600 would be 23:00 hrs on 31st December 1969 while a value of +3600 would be 01:00 hrs on 1st January 1970.
There are different time formats (almost freeform), time zones, daylight saving offsets and who knows what else to consider. The PHP/Unix base date (0) is 00:00 UST on 1st January 1970. Date and time values are nightmare in the world of binary (or decimal at best). For modern projects use something more recent, like the Period library.
This is something difficult to understand. The date () function always use the current timestamp, whether you passed it one or not. Generate range of dates in PHP This code is from ancient PHP 5.2 days.
