Method Desarrolla2\Cache\NotCache::getMultiple() should return iterable but returns false.
Loading history...
Bug Best Practice introduced by
The expression return false returns the type false which is incompatible with the return type mandated by Psr\SimpleCache\CacheInterface::getMultiple() of iterable.

In the issue above, the returned value is violating the contract defined by the mentioned interface.

Let's take a look at an example:

interface HasName {
    /** @return string */
    public function getName();
}

class Name {
    public $name;
}

class User implements HasName {
    /** @return string|Name */
    public function getName() {
        return new Name('foo'); // This is a violation of the ``HasName`` interface
                                // which only allows a string value to be returned.
    }
}
