With these it helps Using the neo4jphp Node/Relationship/Label entities is not required, if you do not wish to use them. If you feel more comfortable using Cypher queries, that is what you should use. Neo4jphp can do Cypher queries. Here are the docs to get you started https://github.com/jadell/neo4jphp/wiki/Cypher-and-gremlin-queries.
It can also handle Cypher transactions https://github.com/jadell/neo4jphp/wiki/Cypher-Transactions

it should still fix some issue You can work around this by downloading the library from GitHub, copy the Everyman folder with its subfolders in your root directory and use what you need. In example
code :
    require("phar://neo4jphp.phar");
    use Everyman\Neo4j\Relationship;

may help you . For relational databases like mysql, transaction handling in PHP is just like. , Check following code.
code :
//$client = Neo4jClient
$transaction = $client->beginTransaction();

$dataCypherQuery = new Query($client, $dataQuery, $params);
// $dataResult = $dataCypherQuery->getResultSet(); // don't do this for transaction
$dataResult = $transaction->addStatements($dataCypherQuery);
//$dataResult = $transaction->addStatements($dataCypherQuery, true);
if (0 == $dataResult->count()) {
    $transaction->rollback();
}
$transaction->commit();

Does that help Not sure what your data looks like, do your sub-menus also have a :MENU label?
I'd probably label all menu nodes with :Menu and then have an additional label for :Main and :Sub
code :
MATCH (m:Menu)-[:IS_PARENT]->(s:Sub)
RETURN m.name, s.name, m:Main
MATCH (m:Main)
MATCH p = (m)-[:IS_PARENT*]->(s:Sub)
RETURN m.name, extract(n in tail(nodes(p)) | n.name) as menus
ORDER BY m.name ASC, length(p) asc

this one helps. I think you get doubles because you have multiple paths (e.g. multiple teams) for the user, use RETURN distinct user
For your import statement, you do it the wrong way round, instead of your approach.
code :
MERGE (user:PERSON {login:{login}})
ON CREATE SET
  user.firstname = {firstname}, user.name= {name}, user.password = {password},
  user.title={title}, user.status = {status}, user.uuid = {uuid}
RETURN user;

may help you . There is no way to specify a page through the REST API; you can only go forward through a paged traversal. Or at least, there is no way to specify a page according to their docs, which are usually pretty thorough: http://docs.neo4j.org/chunked/stable/rest-api-traverse.html#rest-api-creating-a-paged-traverser
This is also true for indexes.
