			0 ignored issues – show Bug introduced 2015-12-14 11:11 UTC by Report Bug Copy Issue Report Since `mapHex()` is declared private, calling it with `static` will lead to errors in possible sub-classes. You can either use `self`, or increase the visibility of `mapHex()` to at least protected. Let’s assume you have a class which uses late-static binding: class YourClass { private static function getTemperature() { return "3422 °C"; } public static function getSomeVariable() { return static::getTemperature(); } } 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 { private static function getTemperature() { return "-182 °C"; } } print YourSubClass::getSomeVariable(); // Will cause an access error. In the case above, it makes sense to update `SomeClass` to use `self` instead: class YourClass { private static function getTemperature() { return "3422 °C"; } public static function getSomeVariable() { return self::getTemperature(); } } Loading history...
