ensureCountIndex() public method

Is a no-op if the generated index is a prefix of an existing one. If you have a similar ensureGetIndex call, call it first.
public ensureCountIndex ( array $fields, boolean $includeRunning ) : void
$fields array fields in count() call to index in same format as \MongoDB\Collection::createIndex()
$includeRunning boolean whether to include the running field in the index
return void
