PHP 5.6 и PHP 7 на русском: Using a Cursor to Get All of the Documents

Using a Cursor to Get All of the Documents

In order to get all the documents in the collection, we will use MongoCollection::find(). The find() method returns a MongoCursor object which allows us to iterate over the set of documents that matched our query. So to query all of the documents and print them out:


<?php
$connection = new MongoClient();
$collection = $connection->database->collectionName;

$cursor = $collection->find();
foreach ( $cursor as $id => $value )
{
    echo "$id: ";
    var_dump( $value );
}
?>

and that should print all 101 documents in the collection. $id is the _id field of a document (cast to a string) and $value is the document itself.
