doctrine one-to-one relation mapping - php

Question

i have two entities that i would like to map them so that when i generate crud for each entity when i want to make a new insert using Map entity to be able to select based on id from Board entity.
I've been trying to make the mapping yet .. i didn't manage not sure if i did it right or not because in mysql i don't see a foreign key after sql generation.

It seams like you haven't read the manual. It is great documentation on both Symfony.com and Doctrine-orm.readthedocs.org.
Read this article (http://symfony.com/doc/current/book/doctrine.html) and use this one as reference (http://doctrine-orm.readthedocs.org/en/latest/reference/association-mapping.html) and you will find the answer to this and many future questions.
What you basically need to do is:
class Board {
/**
* #ORM\ManyToOne(targetEntity="Map")
*/
private $map;
}
