It seems like you code against a concrete implementation and not the interface ArrayAccess as the method count() does only exist in the following implementations of said interface: ArrayIterator, ArrayObject, CachingIterator, PDepend\Source\AST\ASTArtifactList, PDepend\Source\AST\ASTClassOrInterfaceReferenceIterator, Phar, PharData, RecursiveArrayIterator, RecursiveCachingIterator, SplDoublyLinkedList, SplFixedArray, SplObjectStorage, SplQueue, SplStack.

Consider using a different name than the parameter $page. This often makes code more readable.

        if ($page !== null) {
            $component = $page->getComponent($componentName);
        }
