Di PHP, kamu dapat menggunakan library triagens/arangodb untuk menggunakan ArangoDB di dalam kode program PHP. Berikut adalah cara install-nya:

$ cd /path/to/your/project/folder
$ composer require triagens/arangodb

Setelah berhasil mendapatkan modul triagens/arangodb, kamu dapat mulai menggunakan library tersebut di dalam kode PHP atau web framework PHP kamu. Berikut adalah contoh script PHP untuk memeriksa koneksi ke ArangoDB:

<?php

require dirname(__FILE__) . DIRECTORY_SEPARATOR . 'vendor' . DIRECTORY_SEPARATOR . 'autoload.php';

use ArangoDBClient\Connection as ArangoConnection;
use ArangoDBClient\ConnectionOptions as ArangoConnectionOptions;
use ArangoDBClient\UpdatePolicy as ArangoUpdatePolicy;

$connectionOptions =array(
    // server endpoint to connect to
    ArangoConnectionOptions::OPTION_ENDPOINT => 'tcp://127.0.0.1:8529',
    // authorization type to use (currently supported: 'Basic')
    ArangoConnectionOptions::OPTION_AUTH_TYPE => 'Basic',
    // user for basic authorization
    ArangoConnectionOptions::OPTION_AUTH_USER => 'root',
    // password for basic authorization
    ArangoConnectionOptions::OPTION_AUTH_PASSWD => 'root',
    // connection persistence on server. can use either 'Close' (one-time connections) or 'Keep-Alive' (re-used connections)
    ArangoConnectionOptions::OPTION_CONNECTION => 'Close',
    // connect timeout in seconds
    ArangoConnectionOptions::OPTION_TIMEOUT => 3,
    // whether or not to reconnect when a keep-alive connection has timed out on server
    ArangoConnectionOptions::OPTION_RECONNECT => true,
    // optionally create new collections when inserting documents
    ArangoConnectionOptions::OPTION_CREATE => true,
    // optionally create new collections when inserting documents
    ArangoConnectionOptions::OPTION_UPDATE_POLICY => ArangoUpdatePolicy::LAST,
);

// open connection
$connection = new ArangoConnection($connectionOptions);

var_dump($connection);

Bila kita jalankan kode diatas, maka akan muncul output berikut:
