MongoDB\Driver\Cursor::setTypeMap — Sets a type map to use for BSON unserialization

説明

final public MongoDB\Driver\Cursor::setTypeMap(array $typemap): void

Sets the type map configuration to use when unserializing the BSON results into PHP values.

パラメータ

typeMap (array): Type map configuration.

戻り値

値を返しません。

エラー / 例外

Throws MongoDB\Driver\Exception\InvalidArgumentException on argument parsing errors.

When iterating over the cursor, the following exceptions can also be thrown due to an incorrect type map configuration:

Throws MongoDB\Driver\Exception\InvalidArgumentException if a class in the type map cannot be instantiated or does not implement MongoDB\BSON\Unserializable.

例

例1 MongoDB\Driver\Cursor::setTypeMap() example

<?php

$manager = new MongoDB\Driver\Manager("mongodb://localhost:27017");

$bulk = new MongoDB\Driver\BulkWrite;
$id = $bulk->insert(['x' => 1]);
$manager->executeBulkWrite('db.collection', $bulk);

$query = new MongoDB\Driver\Query(['_id' => $id]);
$cursor = $manager->executeQuery('db.collection', $query);
$cursor->setTypeMap(['root' => 'array']);

foreach ($cursor as $document) {
    var_dump($document);
}

?>

上の例の出力は、たとえば以下のようになります。

array(2) {
  ["_id"]=>
  object(MongoDB\BSON\ObjectId)#6 (1) {
    ["oid"]=>
    string(24) "56424fb76118fd3267180741"
  }
  ["x"]=>
  int(1)
}

If you would prefer to have the results returned as an associative array, after executing your query you could call $cursor->setTypeMap like this:

$cursor->setTypeMap(['root' => 'array', 'document' => 'array', 'array' => 'array']);
