- [Voiceover] Hi, I'm David Powers. Welcome to PHP Date and Time Essential Training. PHP has an impressive set of tools designed to take the hard work out of dealing with dates and time. After considering the problems of working with dates and time zones, we'll look at the basic functions inherited from PHP 4, for formatting and creating dates. Then we'll embark on an in depth exploration of the more sophisticated date and time related classes introduced in PHP 5.
You'll learn how to find and set the correct time zone and perform date calculations that automatically take different time zones and daylight saving time into consideration. I'll show you how to find out when the clocks next change in different parts of the world; and how to calculate the time of sunrise and sunset. Need to work out the date of the third Thursday of each month? No problem. PHP has it covered. There's a lot to do, so let's dive straight into PHP Date and Time Essential Training.
Q: How does calculating sunrise and sunset (as shown in chapter 7) work for locations north of the Arctic Circle?
A: In polar regions, date_sun_info() reports the value for sunrise and sunset as 1 on days when the sun never sets. The values are empty for days when the sun never rises.
