(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 $typemap
) : void
Sets the type map configuration to use when unserializing the BSON results into PHP values.
返回值
没有返回值。
错误／异常
- Throws MongoDB\Driver\Exception\InvalidArgumentException on argument parsing errors.
When iterating over the cursor, the following exceptions can also be thrown due to an incorrect type map configuration:
- Throws MongoDB\Driver\Exception\InvalidArgumentException if a class in the type map cannot be instantiated or does not implement MongoDB\BSON\Unserializable.
范例
Example #1 MongoDB\Driver\Cursor::setTypeMap() example
<?php$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)
}
