I think the confusion comes from people reasonably expecting this to work like “this” does in Java or the way people use “self” in Python. Although this is sometimes used to similar effect, it’s nothing like “this” in Java or other languages. And while it’s a little harder to understand, its behavior isn’t magic.

  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...

According to Tech Crunch, Google finally released its Analytics real time API. Although this feature was launched two years ago, there was no convenient way for webmasters to adjust the data so that they can be viewed properly. Now developers can use the API to get what they want and utilize these data to do what they want to. Developers need to apply for using the API now.
