composer dumpautoloadでAutoload反映

using設定

// ArangoDB用
use ArangoDBClient\Collection as ArangoCollection;
use ArangoDBClient\CollectionHandler as ArangoCollectionHandler;
use ArangoDBClient\Connection as ArangoConnection;
use ArangoDBClient\ConnectionOptions as ArangoConnectionOptions;

使用方法

    $connectionOptions = [
        // database name
        ArangoConnectionOptions::OPTION_DATABASE => '_system',
        // 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 => '',
        // connection persistence on server. can use either 'Close' (one-time connections) or 'Keep-Alive' (re-used connections)
        ArangoConnectionOptions::OPTION_CONNECTION => 'Keep-Alive',
        // 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,
    ];
    $connection = new ArangoConnection($connectionOptions);

    // now run another query on the data, using bind parameters
    $statement = new ArangoStatement(
        $connection, [
            'query' => 'FOR i IN 1..2 RETURN { key: i, value: i + @value }',
            'bindVars' => [
                'value' => 10,
            ],
        ],
    );

    // executing the statement returns a cursor
    $cursor = $statement->execute();

    // easiest way to get all results returned by the cursor
    $values = $cursor->getAll();

    // var_dump($values);
    foreach($values as $value) {
        var_dump($value->getAll());
    }

結果

array(2) { ["key"]=> int(1) ["value"]=> int(11) } array(2) { ["key"]=> int(2) ["value"]=> int(12) }
