How to solve the issue and access Neo4J using PHP, Is there any video tutorial for Neo4JPhp

La solution

You aren't including the library anywhere. In PHP, you can't just use classes, you have to include a file which contains that class, or use an autoloader that maps class names to file names (autoloading is the preferred way to do it.)

I suggest installing the library with Composer. There are instructions for this on the neo4jphp wiki: https://github.com/jadell/neo4jphp/wiki/Getting-started. (You will need to install Composer first; instructions available here: https://getcomposer.org/)

Then, in your file, you can do:

<?php
require('vendor/autoload.php');

use Everyman\Neo4j\Client,
    Everyman\Neo4j\Transport,
    Everyman\Neo4j\Node,
    Everyman\Neo4j\Relationship;
