			0 ignored issues – show Bug introduced 2015-12-11 14:38 UTC by Report Bug Copy Issue Report The property `var` does not exist. Did you maybe forget to declare it? In PHP it is possible to write to properties without declaring them. For example, the following is perfectly valid PHP code: class MyClass { } $x = new MyClass(); $x->foo = true; Generally, it is a good practice to explictly declare properties to avoid accidental typos and provide IDE auto-completion: class MyClass { public $foo; } $x = new MyClass(); $x->foo = true; Loading history...

			0 ignored issues – show Compatibility introduced 2015-12-11 14:38 UTC by Report Bug Copy Issue Report `$iterator` of type `object<Traversable>` is not a sub-type of `object<Iterator>`. It seems like you assume a child interface of the interface `Traversable` to be always present. This check looks for parameters that are defined as one type in their type hint or doc comment but seem to be used as a narrower type, i.e an implementation of an interface or a subclass. Consider changing the type of the parameter or doing an instanceof check before assuming your parameter is of the expected type. Loading history...
