// Example of TS.REVRANGE command usage:

// 1. Create time series
$client = new Client();

$createArguments = (new CreateArguments())->labels('type', 'temp', 'location', 'TLV');
$createResponse = $client->tscreate('temp:TLV', $createArguments);

echo "Time series creation status: {$createResponse}\n";

echo "Samples was added with following timestamps: {$stringResponse}\n";

// 3. Query samples by values in the given range
