<?php

  require_once(__DIR__.'/vendor/autoload.php');

use Neoxygen\NeoClient\ClientBuilder;
$client = ClientBuilder::create()
->addConnection('default','http','localhost',7474,true,'neo4j','tarun')
->setAutoFormatResponse(true)
->build();
$query = 'CREATE (user:User {name:"john"})';
$client->sendCypherQuery($query);
$query = 'MATCH (user:User {name:"john"}) RETURN user';
$result = $client->sendCypherQuery()->getResult();
// accessing the user identifier (so the user node) from the result
$john = $result->get('user');
// The $john is a wrapped Node object and have some methods

// The node id
echo $john->getId();
// The labels
print_r($john->getLabels());
// The properties
echo $john->getProperty('name');
$query = 'MATCH (user:User {name:"john"})
CREATE (friend:User {name:"Judith"})
MERGE (user)-[r:FRIEND]->(friend)
RETURN user, friend, r';
$result = $client->sendCypherQuery($q)->getResult();

$john = $result->get('user');
$judith = $result->get('judith');

// What john has for relationships

print_r($john->getRelationships()); // returns relationships objects

// Get a node connected to john

print_r($john->getConnectedNode());
?>

I had a similar issue and the main cause was not using autoload.php, try this:

require_once 'vendor/autoload.php';

It is without __DIR__.

I think existing composer.lock has some mismatched dependencies. rename composer.lock and vendor folder and try "composer install" or "composer update". hope helps.

I was experiencing the same issue when running the CLI web server of my laravel project. I solved that by removing(deleting) the vendor folder completely and ran.

composer install

After all the files where downloaded, it now works just fine.
