Example #1 MongoDB\Driver\Manager::executeQuery() example
<?php
$manager = new MongoDB \ Driver \ Manager ( "mongodb://localhost:27017" );
$bulk = new MongoDB \ Driver \ BulkWrite ;
$bulk -> insert ([ 'x' => 1 ]);
$bulk -> insert ([ 'x' => 2 ]);
$bulk -> insert ([ 'x' => 3 ]);
$manager -> executeBulkWrite ( 'db.collection' , $bulk );
$filter = [ 'x' => [ '$gt' => 1 ]];
$options = [
'projection' => [ '_id' => 0 ],
'sort' => [ 'x' => - 1 ],
];
$query = new MongoDB \ Driver \ Query ( $filter , $options );
$cursor = $manager -> executeQuery ( 'db.collection' , $query );
foreach ( $cursor as $document ) {
var_dump ( $document );
}
?>
以上例程会输出:
object(stdClass)#6 (1) { ["x"]=> int(3) } object(stdClass)#7 (1) { ["x"]=> int(2) }
