MongoDB\GridFS\Bucket::__construct()

Definition

MongoDB\GridFS\Bucket::__construct()

Constructs a new Bucket instance.

function __construct(
    MongoDB\Driver\Manager $manager,
    string $databaseName,
    array $options = []
)

Parameters

$manager : MongoDB\Driver\Manager

The Manager instance from the extension. The manager maintains connections between the driver and MongoDB.

$databaseName : string

The name of the database.

$options : array

An array specifying the desired options.

Name	Type	Description
bucketName	string	The bucket name, which will be used as a prefix for the files and chunks collections. Defaults to "fs".
chunkSizeBytes	integer	The chunk size in bytes. Defaults to 261120 (i.e. 255 KiB).
codec	MongoDB\Codec\DocumentCodec	The default Encode Data with Type Codecs to use for bucket methods that return a file document (e.g. MongoDB\GridFS\Bucket::find()). New in version 1.17.
readConcern	MongoDB\Driver\ReadConcern	The default read concern to use for bucket operations. Defaults to the manager's read concern.
readPreference	MongoDB\Driver\ReadPreference	The default read preference to use for bucket operations. Defaults to the manager's read preference.
typeMap	array	Default type map to apply to cursors, which determines how BSON documents are converted to PHP values. The library uses the following type map by default: [ 'array' => 'MongoDB\Model\BSONArray', 'document' => 'MongoDB\Model\BSONDocument', 'root' => 'MongoDB\Model\BSONDocument', ]
writeConcern	MongoDB\Driver\WriteConcern	The default write concern to use for bucket operations. Defaults to the manager's write concern.

Errors/Exceptions

MongoDB\Exception\InvalidArgumentException for errors related to the parsing of parameters or options.

Behavior

If you construct a Bucket explicitly, the Bucket inherits any options from the MongoDB\Driver\Manager object. If you select the Bucket from a Database object, the Bucket inherits its options from that object.

Examples

<?php
$bucket = (new MongoDB\Client)->test->selectGridFSBucket();
var_dump($bucket);

The output would then resemble:

object(MongoDB\GridFS\Bucket)#3053 (2) {
  ["bucketName"]=>
  string(4) "test"
  ["databaseName"]=>
  string(11) "phplib_test"
}
