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!
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!
Scalar Typehints
In addition to more complex typehints, in PHP 7, we now have the ability to typehint scalars. Let me show you!
Return Type Declarations
If you wish, you may now declare return types for your interfaces and methods.
Spaceships
The "spaceship" operator is definitely confusing at first to understand. Let's review a few examples to figure it out.
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.
Grouped Imports
While not a huge new feature, you now, if you wish, may group your "use" import statements.
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.
