Let’s assume you have a class which uses late-static binding: class YourClass { private static $someVariable; public static function getSomeVariable() { return static::$someVariable; } } 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: class YourSubClass extends YourClass { } YourSubClass::getSomeVariable(); // Will cause an access error. In the case above, it makes sense to update `SomeClass` to use `self` instead: class SomeClass { private static $someVariable; public static function getSomeVariable() { return self::$someVariable; // self works fine with private. } } Loading history...

It seems like you are assigning to a variable which was imported through a `use` statement which was not imported by reference.
