Setting Criteria for a Query
We can create a query to pass to the MongoCollection::find() method to get a subset of the documents in our collection. For example, if we wanted to find the document for which the value of the "i" field is 71, we would do the following:
<?php
$connection = new MongoClient();
$collection = $connection->database->collectionName;
$query = array( 'i' => 71 );
$cursor = $collection->find( $query );
while ( $cursor->hasNext() )
{
var_dump( $cursor->getNext() );
}
?>
Результат выполнения данного примера:
array(2) {
["_id"]=>
object(MongoId)#6 (0) {
}
["i"]=>
int(71)
["_ns"]=>
"testCollection"
}
