この関数にはパラメータはありません。
Returns an associative array containing three fields. The first field is databases, which in turn contains an array. Each element of the array is an associative array corresponding to a database, giving the database's name, size, and if it's empty. The other two fields are totalSize (in bytes) and ok, which is 1 if this method ran successfully.
例1 Mongo::listDBs example
Example demonstrating how to use listDBs and the returned data structure.
<?php
$mongo = new Mongo();
$dbs = $mongo->listDBs();
print_r($dbs);
?>
上の例の出力は、 たとえば以下のようになります。
Array ( [databases] => Array ( [0] => Array ( [name] => doctrine [sizeOnDisk] => 218103808 [empty] => ) ) [totalSize] => 218103808 [ok] => 1 )
