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!
01
قسمت 1
Some Vagrant, Some PHP 7
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!
02
قسمت 2
Scalar Typehints
In addition to more complex typehints, in PHP 7, we now have the ability to typehint scalars. Let me show you!
03
قسمت 3
Return Type Declarations
If you wish, you may now declare return types for your interfaces and methods.
04
قسمت 4
Spaceships
The "spaceship" operator is definitely confusing at first to understand. Let's review a few examples to figure it out.
05
قسمت 5
The Null Coalesce Operator
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.

قسمت 6
Grouped Imports
While not a huge new feature, you now, if you wish, may group your "use" import statements.
07
قسمت 7
Anonymous Classes
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.
