At the end of this guide, you will have created a simple PHP
program that connects to the Memgraph database and executes simple queries.
To follow this guide, you will need:
- A running Memgraph instance. If you need to set up Memgraph, take a look at the Installation guide.
- A basic understanding of graph databases and the property graph model.
- Composer, a tool for dependency management in PHP. Instructions on how to install Composer can be found here.
We recommend using the Bolt driver for PHP.
We'll be using a very simple PHP script in combination with Composer to demonstrate how to connect to a running Memgraph instance.
Let's jump in and connect a simple program to Memgraph.
1. Create a new directory for your application, for example
position yourself in it.
2. Create a
index.php file and add the
following code to it:
require_once __DIR__ . '/vendor/autoload.php';
// Create connection class and specify target host and port
$conn = new \Bolt\connection\Socket();
// Create new Bolt instance and provide connection object
$bolt = new \Bolt\Bolt($conn);
// Build and get protocol version instance which creates connection and executes handshake
$protocol = $bolt->build();
// Login to database with credentials
// Execute query with parameters
$stats = $protocol->run(
'CREATE (a:Greeting) SET a.message = $message RETURN id(a) AS nodeId, a.message AS message',
['message' => 'Hello, World!']
// Pull records from last executed query
$rows = $protocol->pull();
echo 'Node ' . $rows . ' says: ' . $rows;
If you need SSL connection you have to replace
Socket instance with
StreamSocket and enable SSL with additional method.
$conn = new \Bolt\connection\StreamSocket('URI or IP', 7687);
'verify_peer' => true
Library is automatically requesting latest 4 versions. If you need to request other Bolt version you have to call
3. Run a composer command to get the required library:
composer require stefanak-michal/bolt
It will auto create composer.json file.
4. Start the application with the following command:
php -S localhost:4000
You should see an output similar to the following:
Node 1: Hello, World!
Where to next?
