Inserting a Document

Associative arrays are the basic object that can be saved to a collection in the database. A somewhat random "document" might be:

<?php
$doc = array(
    "name" => "MongoDB",
    "type" => "database",
    "count" => 1,
    "info" => (object)array( "x" => 203, "y" => 102),
    "versions" => array("0.9.7", "0.9.8", "0.9.9")
);
?>

Note that you can have nested arrays and objects. The driver will always store an associative array as an object in the database. A numerically indexed array is stored as an array in case the keys start at 0 and are not interrupted, and as an object if the array keys don't start at 0 or have gaps (ie: 0, 1, 4, 5).

To insert this document, use MongoCollection::insert:

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

$collection->insert( $doc );
?>
