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() );
}
?>
O exemplo acima irá imprimir:
array(2) {
["_id"]=>
object(MongoId)#6 (0) {
}
["i"]=>
int(71)
["_ns"]=>
"testCollection"
}
