MongoDB\Driver\Cursor::setTypeMap — Sets a type map to use for BSON unserialization
$typemap): voidSets the type map configuration to use when unserializing the BSON results into PHP values.
typeMap (array)沒(méi)有返回值。
When iterating over the cursor, the following exceptions can also be thrown due to an incorrect type map configuration:
示例 #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);
}
?>
以上例程的輸出類(lèi)似于：
array(2) {
["_id"]=>
object(MongoDB\BSON\ObjectId)#6 (1) {
["oid"]=>
string(24) "56424fb76118fd3267180741"
}
["x"]=>
int(1)
}
