fetchAll() public method

Returns false if no rows matched. ### Options - cache - Returns the cached version of the query, if exists and stores the result in cache. This is a non-persistent cache, and only lasts for a single request. This option defaults to true. If you are directly calling this method, you can disable caching by setting $options to false
public fetchAll ( string $sql, array | boolean $params = [], array $options = [] ) : boolean | array
$sql string SQL statement
$params array | boolean Either parameters to be bound as values for the SQL statement, or a boolean to control query caching.
$options array additional options for the query.
return boolean | array Array of resultset rows, or false if no rows matched
