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)
}
