MongoClient::listDBs() example

Example demonstrating how to use listDBs and the returned data structure.

<?php

$mongo = new MongoClient();
$dbs = $mongo->listDBs();
print_r($dbs);

?>

The above example will output something similar to:

Array
(
    [databases] => Array
        (
            [0] => Array
                (
                    [name] => doctrine
                    [sizeOnDisk] => 218103808
                    [empty] =>
                )
        )

    [totalSize] => 218103808
    [ok] => 1
)
