Creating bi-directional relation between two nodes using the neo4jphp function "relateTo"

Question

I create a relationship as the following in Neo4php

$src->relateTo($dst, 'FRIENDS')
    ->setProperty('duration', '5')
    ->save();

I want the relationship be undirected not directed. If I am not wrong we can do this in Cypher

create n-[:FRIENDS]-m

vs

create n-[:FRIENDS]->m

How about in Neo4jphp? Can we set "relateTo" to a bi-directional relationship?

Answer 1

Neo4j does not support undirected relationships. What you are asking for is impossible. Why do you want undirected relationships? If the direction doesn't make sense for your domain, just pick a direction arbitrarily and ignore it when traversing or querying.
