neo4jphp relateTo() to a getResultSet() object - neo4jphp

Question

I'm using the Neo4jphp REST API and I'm having a problem of relating a node iv created in my code to a node im retrieving from the neo4j database.
I'm retrieving the node as follows
$querystring="MATCH(n)"."WHERE has (n.name) and n.name='Interests'"."RETURN n";
$query=new Everyman\Neo4j\Cypher\Query($client,$querystring);
$result=$query->getResultSet();
im creating another node in my code using createNode()
$friend=$client->makeNode()->setProperty('name',$fname)->save();
I used relateTo() to relate them
$m=$client->getNode($result);
$m->relateTo($friend,$movi)->save();//$movi is a common movie name
but getting this error
PHP Catchable fatal error: Object of class Everyman\\Neo4j\\Query\\ResultSet could not be converted to string in /var/www/vendor/everyman/neo4jphp/lib/Everyman/Neo4j/Cache/EntityCache.php
would really appreciate any input

Answer 1

A neo4jphp query returns a row object (even if theres only one responce) so
$m=$client->getNode($result);
won't work
try this instead
$querystring="MATCH(n) WHERE has (n.name) and n.name='Interests' RETURN n";
$query=new Everyman\Neo4j\Cypher\Query($client,$querystring);
$result=$query->getResultSet();
foreach($result as $resultItem)
{
$resultArray[] = $resultItem['x'];
//$resultItem['x'] is the node object, now $result array is an array of node objects
}
$friend= $client->makeNode()->setProperty('name',$fname)->save();
$resultArray[0]->relateTo($friend,$movi)->save();
this code will also work with this query (easier to read)
$querystring="MATCH (n {name:"Interests"}) RETURN n";

Answer 2

I would do it this way:
$queryString = "MATCH(n) WHERE has (n.name) and n.name= {name} RETURN ID(n)";
$query = new Everyman\Neo4j\Cypher\Query($client,$queryString,array('name'=>'Interests'));
$result = $query->getResultSet();
$resultArray=array();
foreach($result as $row)
{
array_push($resultArray,$row['n']);
}
$friend = $client->getNode($resultArray[0]);
$friend->relateTo($friend,$movi)-save();
