Since $instance is declared private, accessing it with static will lead to errors in possible sub-classes; consider using self, or increasing the visibility of $instance to at least protected.
Let’s assume you have a class which uses late-static binding:
The code above will run fine in your PHP runtime. However, if you now create a
sub-class and call the getSomeVariable() on that sub-class, you will receive
a runtime error:
classYourSubClassextendsYourClass{}YourSubClass::getSomeVariable();// Will cause an access error.
In the case above, it makes sense to update SomeClass to use self instead:
classSomeClass{privatestatic$someVariable;publicstaticfunctiongetSomeVariable(){returnself::$someVariable;// self works fine with private.}}
