I have table options, which have 2 fields (name and value) and 5 rows for example. I need to list all the rows in 5 fields on one page, so i can update every one of them.

I know i have to create collections, but i can’t find simple example with functionality to view and update rows on one page.
First, i need to find all options rows.
$options = $this->getDoctrine()
->getRepository('ACMETestBundle:Option')
->findAll();
What should i do next ? How can i list them in one form ? How can i update every value in database ?
Try this way:
You create an entity (it doesn’t has to be an ORM entity), it will have an options member, which is an
ArrayCollection. Create a form for this entity (http://sf.khepin.com/2011/08/finally-through-symfony2-forms-and-collectiontype-make-it-dynamic/).In the controller you can pass the list of the options to the entity (
$entity->setOptions($options). Now you can render the form, and it will have the collection of the entities. After posting you can get the options ($entity->getOptions()) and save them individually.
