Coding Style introduced by
The visibility should be declared for property $instance.

The PSR-2 coding standard requires that all properties in a class have their visibility explicitly declared. If you declare a property using

class A {
    var $property;
}

the property is implicitly global.

To learn more about the PSR-2, please see the PHP-FIG site on the PSR-2.
