Connect a PHP application to TeselaDB with the official MongoDB driver.

Connect a PHP application to TeselaDB with the official MongoDB driver for PHP. TeselaDB presents itself as a mongos, so the driver works unchanged.

Requirements

PHP with the mongodb extension and Composer.
The address of one or more nodes, a user with readWrite on the database and the pki/ca.pem file of the cluster.

Install the driver

Shell

pecl install mongodb
composer require mongodb/mongodb

Store the connection string

Put the string in an environment variable instead of writing it in the code:

Shell

export TESELADB_URI="mongodb://user:<password>@node-01:27017,node-02:27017/shop?tls=true&tlsCAFile=./ca.pem"

Write and read a document

<?php
require "vendor/autoload.php";

$client = new MongoDB\Client(getenv("TESELADB_URI"));
$orders = $client->shop->orders;
$orders->insertOne(["total" => 149.5]);
echo $orders->countDocuments(), PHP_EOL;

Check

The program prints the number of documents in orders, which grows by one each time you run it.

Common problems

The connection closes before authenticating because tls=true is missing from the string.
The driver does not trust the node certificate because it does not have the CA of this cluster.
