  Convert time to Unix time

Unix time is defined as the number of seconds that have elapsed since midnight Coordinated Universal Time (UTC), 1 January 1970,not counting leap seconds. It is used widely in Unix-like and many other operating systems and file formats. It is neither a linear representation of time nor a true representation of UTC.

  Using DateInterval class in PHP

DateInterval is (amongst others) a relatively new addition to the date extension in PHP 5.3. It allows to describe an interval in time, and you can perform actions with that interval. Basically, it allows to calculate with dates in a very easy way, and do even more fun stuff with it.Unfortunately no documentation exists today for DateInterval and friends, but PHP is open-source so you can easily have a peek at the code to see what’s happening under the engine.

  Dates in PHP and MySQL

I see a lot of people on forums and on my training courses asking about the best way (or any way) to manage dates stored in a MySQL database and used in PHP. Three options follow, but first the problem.PHP uses unix timestamps for all its date functionality. It has methods to convert these timestamps into pretty much any text format you could want but internally it uses the timestamp format. A timestamp is simply an integer. Specifically, it’s the number of seconds that have ela...

The answer is 2018-07-01. Why not 2018-06-30? So people get confused. It appears that this is ...
