PHP anonymous classes use case: testing abstract classes

I recently wanted to test an abstract class that already came with some written out functions.

I ended up with a setup where I had an anonymous class extend the abstract class.

$dependency = new Dependency();
$myClass = new class($dependency) extends AbstractClass {};

As you see, you can also pass in necessary dependencies. Cool, isn’t it!?

Support for anonymous classes was added in PHP 7.
