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: 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 class YourSubClass extends YourClass { }
YourSubClass::getSomeVariable(); // Will cause an access error.
In the case above, it makes sense to update class SomeClass
{
private static $someVariable;
public static function getSomeVariable()
{
return self::$someVariable; // self works fine with private.
}
}

You can fix this by adding a namespace to your class:
When choosing a vendor namespace, try to pick something that is not too generic to avoid conflicts with other libraries.
