MongoDB\Driver\Cursor::setTypeMap

(mongodb >=1.0.0)

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

说明

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

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

参数

typeMap (array): Type map configuration.

返回值

没有返回值。

错误／异常

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.

范例

Example #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);
}

?>

以上例程的输出类似于：

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']);
