Slated for release in December, 2015, PHP 7 brings a wealth of new features, bug fixes, and performance improvements. If you're curious, come with me, as I demonstrate what's new!
Before we can review what's new in PHP 7, we should first get the proper development environment setup. Luckily, Rasmus has done most of the work for us!
In addition to more complex typehints, in PHP 7, we now have the ability to typehint scalars. Let me show you!
If you wish, you may now declare return types for your interfaces and methods.
The "spaceship" operator is definitely confusing at first to understand. Let's review a few examples to figure it out.
Remember the days of checking whether a variable 'isset', and using the result to respond in one of two ways? Cumbersome would be an understatement! Luckily, with PHP7, the process is much simpler.
While not a huge new feature, you now, if you wish, may group your "use" import statements.
Much like anonymous functions, in PHP 7, you now have the ability to create anonymous classes. They're definitely not for everything, but you might find some good use-cases from time to time.
این دوره هنوز به پایان نرسیده است و در آینده درس های دیگری به آن افزوده خواهد شد.
