			0 ignored issues – show Coding Style Compatibility introduced 2016-03-20 06:18 UTC by Report Bug Copy Issue Report PSR1 recommends that each class must be in a namespace of at least one level to avoid collisions. You can fix this by adding a namespace to your class: namespace YourVendor; class YourClass { } When choosing a vendor namespace, try to pick something that is not too generic to avoid conflicts with other libraries.

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...

Documentation Bug introduced 2016-03-20 06:18 UTC by Report Bug Copy Issue Report It seems like `new static()` of type `this<DynamicCSSCompiler>` is incompatible with the declared type `object<Singleton>` of property `$instance`. Our type inference engine has found an assignment to a property that is incompatible with the declared type of that property. Either this assignment is in error or the assigned type should be added to the documentation/type hint for that property.. Loading history...
