// options：host part auth timeout reserved retry_interval read_timeout database 
$bloomFilter = new BloomFilter();
$bloomFilter = new BloomFilter(['host' => '192.168.20.6']);
$bloomFilter = new BloomFilter(['host' => '192.168.20.6', 'port' => 6379]);
$bloomFilter = new BloomFilter(['host' => '192.168.20.6', 'port' => 6380, 'auth' => 123456]);

$bloomFilter->setConfig('127.0.0.1', 6379, null);
$bloomFilter->setHost('127.0.0.1');
$bloomFilter->setPort(6379);

// 新建过滤器 $errorRate：容错率取值范围(0,1) $capacity：容量
$bool = $bloomFilter->reserve('key', 0.001, 1000);
// 过滤器添加单个值
$bool = $bloomFilter->add('key', 'value');
$bool = $bloomFilter->insert('key', 'value');
// 过滤器添加多个值
$array = $bloomFilter->madd('key', ['value1','value2','value3']);
// 检测过滤器是否存在单个值
$bool = $bloomFilter->exists('key', 'value');
// 检测过滤器是否存在多个值
$array = $bloomFilter->mexists('key', ['value1','value2','value3']);
// 获取 Redis 配置参数
$config = $bloomFilter->getConfig();
