README

This library contains wrapper class to cover basic functionality with Bolt library.

Usage

Memgraph::$auth = ['scheme' => 'none'];
$rows = Memgraph::query('RETURN $n as num', ['n' => 123]);

You can also use methods like queryFirstField and queryFirstColumn.

If you want to learn more about available query parameters check tests.

Database server

Default connection is executed on 127.0.0.1:7687. You can change target server with static properties:

Memgraph::$host = '127.0.0.1';
Memgraph::$port = 7687;

Transactions

Transaction methods are:

Memgraph::begin();
Memgraph::commit();
Memgraph::rollback();

Log handler

You can set callable function into Memgraph::$logHandler which is called everytime query is executed. Method will receive executed query with additional statistics.

Check class property annotation for more information.

Error handler

Standard behaviour on error is trigger_error with E_USER_ERROR. If you want to handle Exception by yourself you can set callable function into Memgraph::$errorHandler.

Statistics

Wrapper offers special method Memgraph::statistic(). This method returns specific information from last executed query.

Check method annotation for more information.
